However, the carbon steel matrix is easy to corrode in the circulating cooling water, which shortens its service life. In this study, a new highly efficient benzotriazole-based (BMN) composite inhibitor was synthesized and investigated against the corrosion of carbon steel in stone processing wastewater. The corro- sion inhibition properties and mechanism of prepared BMN for carbon steel in real stone processing wastewater were evaluated and deduced using the experimental weight loss, electrochemical and surface morphology characterization techniques. Weight loss methods results showed that a high inhibition efficiency of 99.59% in stone processing wastewater was achieved at ambient temperature, with the stirring speed 200 rpm, the immersion time 7 d, and the BMN concentration is 50 mL·L –1 . Electrochemical impedance spectroscopy indicated that resistance from the surface films ( R 2 ) and charge transfer resistance ( R 3 ) were enhanced with increase in BMN concentration. Polarisation results revealed the BMN acted as an anodic inhibitor, owing to the addition of BMN resulted in the significant change of anodic Tafel slopes ( β a ). Scanning electron microscopy results indicated BMN formed a protective film on the surface of carbon steel through adsorption. In short, the prepared BMN composite inhibitor exhibited superior anti-corrosion performance for saw blade corrosion in stone processing wastewater, which had great application potential in industries.","PeriodicalId":11260,"journal":{"name":"Desalination and Water Treatment","volume":"70 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84423349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nanocomposites were characterized through energy-dispersive X-ray, X-ray diffraction analysis, scanning electron microscopy, Fourier-transform infrared spectrophotometry, zero-point charge (pH pzc ) and thermogravimetric/differential thermal analysis. For the demonstration of adsorption efficiency of the nanocomposite, batch adsorption experiments were carried out. Maximum removal of selected pollutant was achieved in 30 min. Several kinetic and isotherm models were applied to the sorption kinetics and isothermal data. The pseudo-sec-ond-order kinetics fitted well the data. The X max (maximum adsorption) at 50°C was recorded as 14.025 mg/g with K 2 (pseudo-second-order kinetics constant) value of 0.0162 and R 2 value of 0.99. The adsorption isotherm data fitted well the Langmuir isotherm model. The optimum pH for the removal of lambda-cyhalothrin was achieved at pH 5. 0.1 g of PMCNC was used as optimum dose in all experiments. The negative value of Gibbs free energy reveals that the removal of lambda-cyhalo-thrin is a spontaneous process. Due to the excellent adsorption capability and easy separation from slurry after use through the application of magnet the PMCNC can be effectively used as an effective sorbent alternative to activated carbon for the removal of inorganic and organic contaminants from aquatic media. This nanocomposite could compete with other adsorbents in the field of surface chemistry warranting further experimentation.","PeriodicalId":11260,"journal":{"name":"Desalination and Water Treatment","volume":"56 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83406236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chemical and structural analysis indicated that EHRC and raw corncob had numerous active functional groups and a large, rough adsorption surface. These properties, more prominent in EHRC, underlined the material’s efficiency in dye adsorption. EHRC and raw corncob were more favorable for the adsorption of methylene blue (MB) than methyl orange. The adsorption capacities of both EHRC and raw corncob increased with increasing initial dye concentration, and adsorption occurred rapidly. The adsorption capacity of EHRC did not change much when the solution pH was greater than the pH at point zero charge (pH PZC , 3.78). The process modelling demonstrated that adsorption of MB onto EHRC well fitted by the pseudo-second-order and Langmuir isotherm models. The adsorption was a spontaneous exothermic reaction based on thermodynamic analysis. These results showed that EHRC could be used as an efficient and cheap adsorbent.","PeriodicalId":11260,"journal":{"name":"Desalination and Water Treatment","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134884121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
