Chromium (VI) is a prevalent hazardous heavy metal ion found in industrial wastewater, significantly affecting the environment. This research details the fabrication and examination of an innovative Fe₃O₄-Formaldehyde-Urea resin (Fe₃O₄@FUR) for the effective removal of hexavalent chromium (Cr(VI)) from water-based solutions. Fe₃O₄@Formaldehyde Urea Resin presents a highly original and green chemistry approach by combining the magnetic properties of Fe₃O₄ with a less-toxic resin matrix, enabling numerous sustainable applications in environmental remediation. The Fe₃O₄@FUR exhibited a high maximum adsorption capacity (qmax) of 79.6 mg/g at pH 1. Kinetic results demonstrated that Cr(VI) adsorption on Fe₃O₄@FUR followed a pseudo-second-order model. Several characterization methods, including particle size analysis, infrared spectroscopy, scanning electron microscopy, TG-DSC, and XRD, proved that the Fe₃O₄ nanoparticles were successfully integrated into the formaldehyde-urea resin matrix. The stability and reusability of Fe₃O₄@FUR were evaluated by four rounds of regeneration testing. The proposed method is reliable for Cr(VI) sorption in pond, dam, and river water samples.</div></div>","PeriodicalId":101197,"journal":{"name":"Sustainable Chemistry One World","volume":"5 ","pages":"Article 100045"},"PeriodicalIF":0.0,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143517","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}
