Waterborne heavy metals pose significant threats to both the environment and public health, causing neurological damage, developmental disorders, organ cancer. It is essential address contamination of various water bodies by these hazardous substances due their persistent nature lack biodegradability. This review thoroughly explores traditional modern strategies utilized remedy sources contaminated with evaluates effectiveness potential scalability each method. A literature survey reveals several effective for removing from water: adsorption, flotation, ion exchange, chemical precipitation, membrane-based filtration, coagulation, flocculation, phytoremediation, electrochemical methods. In our examination, we discussed agents/adsorbents used, efficiency removal technique, operating conditions, intrinsic advantages disadvantages approach. Summarizing key findings, noted a focus on adsorption techniques; however, challenges include selectively diverse ions, prolonged retention times, cycling stability. While membrane methods are practical, issues like large-volume sludge formation exist. Although electrical-based appear promising, solutions needed industrial-scale separation as well. Prioritizing real wastewater samples in studies crucial. Future research should emphasize eco-friendly, cost-effective

Advances in Heavy Metal Extraction Using Organophosphorus Compounds: A Comprehensive Review

Metals, Journal Year: 2025, Volume and Issue: 15(5), P. 524 - 524

Published: May 6, 2025

Organophosphorus compounds (OPC) are a large class of organic that provide wide range applications, and their importance has grown steadily in recent years. In each category family, these have similarities differences. Due to immense variety, chemicals various properties and, therefore, applications. fact, works been published recently present the main applications OPC, especially metal extraction. Despite extemsive use, optimizing performance as extractant agents remains challenge due structural variability sensitivity process parameters. This review provides critical analysis pentavalent OPCs, focusing on how chemical nature influences heavy extraction efficiency. For first time, we novel classification system for OPCs based phosphorus valency heteroatom coordination, offering framework guide future research. Our findings reveal direct coordination heteroatoms such oxygen, sulfur, nitrogen great influence physicochemical characteristics observation is line with Pearson’s Hard Soft Acids Bases (HSAB) theory sense it demonstrates altering alters affinity ligand. As result, modifications can improve by up 40% some metals, highlighting potential optimized molecular designs maximize industrial future, this work offers solid foundation studies rational design organophosphorus-based extractants. Using HSAB our system, researchers rationally target unparalleled precision. These results transformative impacts recovery efficiency-intensive sectors like mining, waste recycling, clean energy technologies.
