紫外光催化氧化在环境水质分析中的应用

Application of UV-photocatalytic Oxidation in Environmental Water Analysis

紫外光催化氧化是近年来环境水质分析中采用的一种样品预处理新技术,目前在国内环境监测领域还应用得不多。本文结合笔者近期的工作,介绍了紫外光催化氧化的原理、特点、设备及其在环境水质分析中的应用,并简介了微波辅助紫外光催化氧化和超声波_紫外光氧化两种最新技术。

UV-photoeatalytic oxidation is a novel pretreatment technique for environmental water analysis, but this technique has been seldom used in domestic environmental monitoring field. Based on the author＇s recent work, the application and development of UV-photocatalytic oxidation in environmental water analysis, including the technique principle, features, devices, and applications were introduced. Especially, two novel techniques combined with UV-photocatalytic oxidation, i. e microwave assisted UV-photocatalytic oxidation and ultrasonic UV-pbetocatalytic oxidation, were described.
