摘要

高级氧化法(AOPs)在微污染物的降解中得到了广泛的应用。在AOPs中，羟基自由基与微污染物(kOH)二级反应速率常数的重要性是不容置疑的。AOP对微污染物的可降解性可以通过其kOH和其他物理化学性质来预测，因此对水处理链的设计很重要。此外，已知kOH值的微污染物可以作为评价AOPs的探针化合物。本文对212种微污染物的kOH进行了综述。还概述了羟基自由基的产生，kOH的意义，以及用于测定kOH的典型方法。

Reaction Rate Constants of Hydroxyl Radicals with Micropollutants and Their Significance in Advanced Oxidation Processes

Advanced oxidation processes (AOPs) have gained popularity and are being extensively used for the degradation of micropollutants. The importance of 2nd order reaction rate constant of hydroxyl radicals with micropollutants (kOH) in AOPs is undisputable. The degradability of a micropollutant by an AOP can be predicted from its kOH along with other physicochemical properties, and hence are important for the design of water treatment chains. Furthermore, a micropollutant with known kOH value can be used as a probe compound to assess AOPs. In this work, the kOH of 212 micropollutants are reviewed. An overview is also provided on the generation of hydroxyl radicals, significance of kOH, and the typical methods used to determine kOH.

期刊介绍： The Journal of advanced oxidation technologies (AOTs) has been providing an international forum that accepts papers describing basic research and practical applications of these technologies. The Journal has been publishing articles in the form of critical reviews and research papers focused on the science and engineering of AOTs for water, air and soil treatment. Due to the enormous progress in the applications of various chemical and bio-oxidation and reduction processes, the scope of the Journal is now expanded to include submission in these areas so that high quality submission from industry would also be considered for publication. Specifically, the Journal is soliciting submission in the following areas (alphabetical order): -Advanced Oxidation Nanotechnologies -Bio-Oxidation and Reduction Processes -Catalytic Oxidation -Chemical Oxidation and Reduction Processes -Electrochemical Oxidation -Electrohydraulic Discharge, Cavitation & Sonolysis -Electron Beam & Gamma Irradiation -New Photocatalytic Materials and processes -Non-Thermal Plasma -Ozone-based AOTs -Photochemical Degradation Processes -Sub- and Supercritical Water Oxidation -TiO2 Photocatalytic Redox Processes -UV- and Solar Light-based AOTs -Water-Energy (and Food) Nexus of AOTs
