摘要

摘要: 邻苯二甲酸酯类（PAEs）作为水中常见的环境激素对人类以及水中生物具有一定的危害，被各国列为"优先控制污染物"。基于此，设计合成出系列多金属氧酸盐（POMs）材料Ag_xH_5-xPMo₁₀V₂O₄₀，x=1~5，并采用湿法过氧化氢氧化法实现对邻苯二甲酸二乙酯（DEP）的高效氧化降解。该体系中，反应20 min DEP降解率可达到91.0%，TOC和COD去除率分别达到70.2%和81.1%，降解产物为低毒的乳酸、CO₂和H₂O等。实验过程中，催化剂具有较高的活性、稳定性及循环使用性，且表现出较高的底物适应性以及微量底物的去除性。

Abstract: Phthalates (PAEs), as common environmental hormones in wastewater, are listed as "priority control pollutants" by many countries due to the great threat to human beings and organisms in water. A series of polyoxometalate-based materials (Ag_xH_5-xPMo₁₀V₂O₄₀, x =1~5) were designed and synthesized, and the catalytic wet peroxide oxidation (CWPO) was employed to realize the efficient oxidation of diethyl phthalate (DEP) with degradation efficiency of 91.0% at 20 min. Furthermore, the degradation products of DEP were low toxic of lactic acid, CO₂ and H₂O, while the removal efficiency of total organic carbon and chemical oxygen demand achieved 70.2% and 81.1%, respectively. Overall, the catalyst exhibited high activity, stability and recyclability, which showed great tolerance for different phthalates and excellent removals for trace DEP.
