The effects of the loading ratio, 3VRM dosage, pH, and ionic strength on the Cu(II) adsorption capacity of 3VRM were determined. The samples were characterized by scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). SEM analysis revealed that spherical nanoscale manganese dioxide with a plum pattern was attached to the surface of VR, effectively increasing the specific surface area and number of reactive sites on the adsorbent. The main components of volcanic rocks are schistose and foshagite; manganese dioxide also exists in an amorphous form. Manganese dioxide is stable in the form of Mn4+ before and after adsorption. The results revealed that 3VRM had the greatest effect on Cu(II) adsorption at a loading ratio of 3 : 1, dosage of 2.5 g/L, and pH of 4–6. The Cu(II) adsorption capacity of 3VRM was shown to fit well with the pseudo-first-order kinetic model and the Freundlich model. The reaction equilibrium time was 10 min, and the theoretical maximum adsorption amount reached 434.7 mg/g. The acidity of the solution had less effect on the 3VRM, so it could be used in a wide pH range of 3–6. Studies of ion exchange and surface complexation have shown that the material demonstrated high efficiency in removing copper ions. Owing to its good adsorption performance and high efficiency, it is expected to be used for copper-containing wastewater treatment in the future.","PeriodicalId":680,"journal":{"name":"Journal of Water Chemistry and Technology","volume":"47 2","pages":"131 - 143"},"PeriodicalIF":0.5,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The groundwater suitability for irrigational uses was evaluated based on significant water quality parameters and indices. The study highlights that except for a few parameters and indices for selected parts of the region, most of the samples were found under suitable categories. Few samples with elevated electrical conductivity values and higher sodium concentrations signify the possibility of alkalinity and salinity hazards for prolonged uses of groundwater for irrigation. The study witnessed the presence of saline aquifer in the region where samples exhibit higher salinity (>1000 ppm) and can potentially cause salinity hazards for prolonged uses of groundwater for irrigation. The hydrogeochemical classification reveals the dominance of the ({text{HCO}}_{3}^{ - })-Ca2+ type of water followed by mixed-type water due to rock weathering dominance during both seasons.

Moreover, the research findings illustrate that the highest removal of sulphate ions by adsorption occurs at the pH condition of 7. The study indicates that the presence of interfering anions such as phosphate, nitrate, chloride, fluoride, and bicarbonate notably impact the adsorption phenomenon of sulphate ions by CHAC. The study of various kinetic models, including the pseudo-first-order, pseudo-second-order, intra-particle diffusion, Bangham’s pore diffusion, and Elovich’s equation, illustrated the chemical kinetics of the adsorption phenomenon of CHAC. It was observed that the pseudo-second-order model demonstrated the most accurate fit for the kinetics studies with the r2 value of 0.999.

Approximately 97% (93 800 million m3/year) are consumed by irrigated agriculture, whereas the other sectors, such as urban utilities and industry consume ~2700 million m3/year. Climatic changes towards warming will not only reduce the available water sources, but also increase the demand for them from agricultural crops, as higher temperatures increase the evaporation rate. It is expected that the total deficit of water in the two main rivers of Central Asia (Syr Darya and Amu Darya) in 2050 will attain 43 km3/year. Moreover, the monthly runoff regimes will essentially change. The total irrigated area of the Syr Darya River basin is 3.4 million ha, and the total use of the natural Syr Darya basin runoff is 30–150%. According to preliminary forecasts, the population in the Central Asia region is expected to grow by 30% to 2050 as compared to 2015 to attain >88 millions of people, so the areas of irrigated lands are planned to expand to solve the problem of food security in each country of this region. By 2025, the area of irrigated lands in the region must attain 11.8 million ha. This means that a lack of water will lead to the extended use of backwater for irrigation. This paper is devoted to studying the dynamics of the chemical composition of the Syr Darya River from the point of crossing the Tajikistan border to the point of passing to the neighboring Uzbekistan territory. Using the results of the chemical analyses of water samples, an attempt to estimate the utilization of water from the Syr Darya River for irrigation has been made. It has been established that, according to the principal indicators, just the content of adsorbed, soluble, and exchangeable sodium in the Syr Darya River fully meets the requirements to irrigation water.","PeriodicalId":680,"journal":{"name":"Journal of Water Chemistry and Technology","volume":"47 2","pages":"204 - 211"},"PeriodicalIF":0.5,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In paint and coating production, water becomes contaminated with various organic solvents, including butyl glycol, acetic acid, acetylacetone, and others. Efficient treatment and reintegration of this water into the technological process represent critical objectives. This study reports the results of single-stage liquid-phase wastewater treatment under the influence of a magnetic field with a magnetic induction of 20 mT, achieving purification efficiencies of 99.3% for butyl glycol, 99.1% for acetic acid, and 99.8% for acetylacetone. Isopropyl alcohol served as the extractant. The volumetric flow rates of wastewater and extractant were 3.0 and 0.3 dm3/h, respectively. The diameter of the extractor and the openings through which the extractant passes were dextr = 0.03 m and dop = 0.5 mm, respectively. Using a differential cell model, the concentrations of components in equilibrium phases along the height of the apparatus were calculated, along with the number of theoretical stages and the extractor height. The concentrations of components in the raffinate at the 20th cell were nearly identical to their initial concentrations, leading to the assumption of 20 theoretical stages. Given that the distance between theoretical stages is Δh = 0.05 m, the height of the extractor, with a diameter of 0.03 m, was calculated to be Hextr = 20 × 0.05 = 1.0 m. The degree of component extraction along the height of the extractor was also calculated. A zero-waste technology was proposed for treating wastewater contaminated with organic solvents to achieve maximum permissible concentrations (MPCs) using single-stage liquid–liquid extraction under the action of a magnetic field.","PeriodicalId":680,"journal":{"name":"Journal of Water Chemistry and Technology","volume":"47 2","pages":"181 - 187"},"PeriodicalIF":0.5,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many papers are devoted to the modeling of photocatalytic oxidation systems, but they insufficiently highlight the effect of ultraviolet radiation on the processes occurring in the reactor when water structures in the surface water microlayer are activated. For this reason, the development of a model of calculating the effective radiation and energy effect parameters as a function from the absorbance of a treated liquid and the size of a reflector for surface irradiating water treatment systems is relevant. Just the vacuum ultraviolet quantity is a crucial factor in the synthesis of hydroxyl and peroxyl radicals immediately in water. In this paper, theoretical models and algorithms are proposed for the calculation of photocatalytic water treatment reactors with non-immersed radiation sources in the optimal UV radiation utilization regime. The applied oxidizers are known reagents, such as hydrogen peroxide, ozone, etc. Among all the reagents, ozone has the highest oxidation potential in water treatment. The possibilities of water treatment under the cumulative effect of photocatalytic ozone and UV radiation with the use of corresponding excimer lamps have been determined. For the system of irradiation with non-immersed light sources, it seems most promising to use photocatalytic ozone formed from oxygen under the influence of UV light radiation with wavelengths of 100–200 nm.","PeriodicalId":680,"journal":{"name":"Journal of Water Chemistry and Technology","volume":"47 2","pages":"105 - 114"},"PeriodicalIF":0.5,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
