Polymer Hydrogels as Heterogeneous Fenton Oxidation Catalysts for Water Treatment
摘要
Abstract
Fenton oxidation represents a pivotal technology in the domain of water treatment,demonstrating efficacy in the removal of pollutants such as chemical oxygen demand(COD),suspended solids,and heavy metals.However,the low solubility product constant of iron hydroxide(2.8×10-39)at pH levels exceeding 3.0 hinders dissolution of iron ions utilised as conventional Fenton oxidation catalysts.This phenomenon results in the formation of iron-rich sediment,thereby diminishing the efficacy of the hydrogen peroxide reaction.To enhance Fenton oxidation efficiency,the pH of the wastewater may need to be adjusted to 2.5~3.0,necessitating the use of additional alkaline substances in the subsequent stages to meet the pH requirements for external drainage.Therefore,this approach is associated with high costs,management difficulties and safety challenges.The present review focused on the potential application of polymer hydrogels as novel Fenton catalysts,and discussed the progress and challenges in environmental remediation.The heterogeneous Fenton method and its significance in wastewater treatment were systematically introduced.The article provided a detailed analysis of research on polymer-supported heterogeneous Fenton catalysts,including key components such as iron oxide,copper complexes/nanoparticles,and ruthenium.The synthesis methods for high-density metal doping were examined in detail,and the effects of operational parameters,such as catalyst dosage,pollutant concentration,and pH value on process efficiency were thoroughly examined.By highlighting the latest advancements in heterogeneous Fenton oxidation catalysts,the article underscored significant achievements in the design and practical application of new Fenton oxidation catalysts.The article also offered key recommendations for improving the stability and reusability of these catalysts,providing a roadmap for future development in this area.关键词
