Phenolic compounds, prevalent in industrial wastewater, are highly toxic to humans and aquatic life. The removal efficiency of 4-Nitrophenol (PNP) and 4-Chlorophenol (PCP) was examined using batch adsorption experiments under varying conditions including adsorbent dose, contact time, initial concentration, and temperature. Coconut husk was chemically activated and characterized for its adsorption properties. The optimal adsorbent dose for PNP removal was determined to be 0.2 g, achieving a maximum adsorption capacity of 64.65 mg/g after 120 minutes. Adsorption data were fitted to pseudo-first-order and pseudo-second-order kinetic models to understand the adsorption mechanism. The results indicated that the adsorption of PNP onto CHAC followed the pseudo-second-order kinetic model, suggesting chemisorption as the dominant process. The findings demonstrate that activated carbon from coconut husk can be an effective and sustainable adsorbent for removing phenolic derivatives from wastewater, offering a potential solution for environmental detoxification. Further studies on isotherm models and thermodynamics are recommended to optimize the adsorption process for large-scale applications.","PeriodicalId":14371,"journal":{"name":"International Research Journal of Pure and Applied Chemistry","volume":"10 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141923163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mechanical properties; tensile strength, load at break, modulus and water absorption properties were investigated and results compared with control (untreated fibre). The results of the mechanical properties showed that the tensile strength of the fibre (Raphia farinifera) improved from 50.1142MPa for the untreated fibre to 132.3482MPa for potassium hydroxide treatment and 146.0181MPa for hydrogen peroxide treatment. Benzoyl peroxide treatment showed superior load at break value (25.5617N) over the untreated fibre (14.7847N). The results of water absorption showed that the treatment of the fibre reduced the hydrophilic nature of this fibre.

The release of effluents containing colors into water bodies become as a basic ecological worry lately. Regular treatment strategies are insufficient in wiping out these steady and risky poisons, requiring the investigation of novel methodologies. In this review, Cu-doped FeO nanoparticles were easily blended by using a co-precipitation strategy, and their synthetic qualities were entirely analyzed. These nanoparticles showed extraordinary adsorption abilities in the corruption of various color compounds. In particular, manufactured acidic color was focused on for expulsion utilizing metal-doped nanoparticles. Ideal boundaries for maximal acidic color not set in stone by surveying the adsorbent portion, beginning color focus, contact time, and temperature. The pH was distinguished as a critical variable, with the best incentive for maximal adsorption of Congo Red Dye viewed as less than 7. As indicated by late discoveries, Cu/FeO nanoparticles displayed unrivalled adsorption limit with regards to Congo Red Dye color at an ideal pH of 2, a measurement of 0.5 g/500 mL, a contact season of an hour and a half, and a color centralization of 150 ppm at 35° centigrade.

The aim of this research is to evaluate levels of iodine intake by ten Nigerian vegetables using copper complex. Dry alkaline ash method was used in the determination. The results obtained showed that all the ten vegetables used absorbed high concentrations of iodine when inoculated with 0.09 M and 0.14 M [Cu(I)4]2- . Iodine phytotoxicity was observed in all the plants when inoculated with 0.2-0.8 M of the copper complex as all the plants died. Increase in the concentration of copper complex from 0.09-0.14 M increased the absorption of iodine by Amaranthus hybridus, Corchorous olitoruis, Gongronema lotifolium and Solanum melongena. The reverse was observed with Murraya koenigii, Ocimum gratissimum, Talinium triangulare, Abelmoschus esculentus, Cucurbita pepo and Telfairia occidentalis. Ocimum gratissimum absorbed the iodine at 0.09M with value of 164.79 mg/kg, the vegetable also absorbed least at 0.14 M with a dose of 61.80 mg/kg. The intake of the iodine by the plants showed that the method can be used in the fortifying these Nigerian vegetables with iodine, thereby reducing the incidence of Iodine deficiency disorder in humans.","PeriodicalId":14371,"journal":{"name":"International Research Journal of Pure and Applied Chemistry","volume":"17 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140666242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Samples were collected randomly from the market, representative portion of the samples was chopped into small pieces and blended using a blender..Quantitative determination of the pesticide for Herbicides, organochlorine and organophosphate was carried out using Gas Chromatography-Mass Spectrometer after liquid-liquid extraction. Trace Metal was determined using Inductively coupled plasma - optical emission spectrometry (ICP-OES). The results reveal the presence of pesticide residues in all the samples. The mean concentration of pesticides in the samples was below the maximum residue limits (MRs) value for World health organization (WHO) while some were higher. The results also shows that all the trace metals analyzed are present in the samples except for Cadmium which is below the detection limit while Lead and Cobalt are only detected in one sample each.
