苝酰亚胺有机超分子光化学高级氧化体系选择性去除地下水中酚类污染物OA
Perylene Diimide-Based Organic Supramolecular Photochemical Advanced Oxidation System for Selective Removal of Phenolic Pollutants in Groundwater
构建了基于苝酰亚胺(PDI)有机超分子半导体材料与三价铁离子(Fe3+)的光化学高级氧化体系(Fe3+/PDI体系),以实现对地下水中酚类污染物的高效选择性降解.在可见光照射下,Fe3+/PDI体系可在5 min内实现对双酚A(BPA)的快速降解,降解速率较纯PDI体系提升了两个数量级(100多倍);其光催化降解性能基本不受腐殖酸及盐离子的影响,具有较好的稳定性及抗干扰能力.在对某石化场地酚类污染地下水样品的去除实验中发现,该体系可以去除此类水中90％以上的酚类污染物,同时整体总有机碳(TOC)去除率达到40％,为有效和环保地去除地下水中有机污染物提供借鉴.
A photochemical advanced oxidation system(Fe3+/PDI system)was constructed using perylene diimide(PDI)organic supramolecular semiconductor materials combined with ferric ions(Fe3+),aiming to achieve efficient and selective degradation of phenolic pollutants in groundwater.Under visible light irradiation,the Fe3+/PDI system could rapidly degrade bisphenol A(BPA)within 5 min,and the degradation rate was improved by two orders of magnitude(more than 100 times)compared with the pure PDI system.The photocatalytic performance was barely affected by humic acid and salt ions,showing good stability and anti-interference ability.In the removal experiments of phenolic-contaminated groundwater samples from a petrochemical site,this system could remove more than 90％of phenolic pollutants,with a total organic carbon(TOC)removal rate of 40％.This study provides a reference for the effective and environmentally friendly removal of organic pollutants in groundwater.
