铁铜钴-水凝胶非均相催化剂的制备及降解性能研究

Synthesis and Degradation Performance Study of Iron-Copper-Cobalt Hydrogel Heterogeneous Catalyst

芬顿反应因其操作方便、反应效率高在废水处理领域备受关注。本研究通过结合原位自由基共聚交联技术和浸泡法,合成铁铜钴-水凝胶非均相芬顿催化剂。它成功地克服了传统芬顿反应对废水pH值的苛刻要求及反应过程中产生污泥沉淀的问题。以表面活性剂(脂肪醇聚氧乙烯醚)作为目标污染物,在pH值为6.0~7.0的条件下,经过120min的处理,铁铜钴-水凝胶/过氧化氢体系对废水中的TOC和COD_(Cr)的去除率分别达到了89%和93%。这表明该体系成功地解决了传统芬顿反应中存在的pH值和沉淀问题,为非均相催化剂在废水处理领域提供了有益的参考。

The Fenton reaction has garnered significant attention in wastewater treatment due to its convenient operation and high reaction efficiency.This study successfully synthesized an FeCuCo-Hydrogel heterogeneous Fenton catalyst by combining in-situ free radical co-polymerization cross-linking technology with the immersion method.This catalyst effectively overcame the strict pH requirements and sludge precipitation issues associated with traditional Fenton reactions in wastewater treatment.Targeting a surfactant(AEO-9)as the model pollutant,under conditions with a pH range of 6.0~7.0,after 120 minutes of treatment,the FeCuCo-Hydrogel/H_(2)O_(2) system exhibited removal rates of 89% for TOC and 93% for COD_(Cr) in wastewater.This indicates that the system has successfully addressed the pH and precipitation issues present in traditional Fenton reactions,offering valuable insights for the application of heterogeneous catalysts in the field of wastewater treatment.
