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.

In this study, the copper-catalyzed Fenton-like reaction in the presence of bicarbonate (i.e., the Cu(II)/HCO3−/H2O2 system) was examined for the phenol degradation. The rate of phenol degradation by the copper-catalyzed Fenton-like reaction ([Cu(II)]0 = 0.1 mM, [H2O2]0 = 10 mM, pH = 10) was accelerated by 17-fold in the presence of 50 mM HCO3−. The rate of phenol degradation by the Cu(II)/HCO3−/H2O2 system increased with increasing doses of Cu(II) and HCO3−, but showed an optimal value for the H2O2 dose and pH at 5 mM and 10, respectively. The Cu(II)/HCO3−/H2O2 system was selective in degrading phenolic compounds; benzoic acid was resistant to degradation. Cu(III) species (likely complexed forms with carbonate) are believed to be the reactive oxidants responsible for the phenol degradation by the Cu(II)/HCO3−/H2O2 system. Meanwhile, aerating CO2 gas successfully accelerated the phenol degradation by the copper-catalyzed Fenton-like reaction, implying that CO2 aeration can be a practical option to supply bicarbonate when implementing the Cu(II)/HCO3−/H2O2 system.
在本研究中，研究了在碳酸氢盐存在下(即Cu(II)/HCO3−/H2O2体系)铜催化的类fenton反应对苯酚的降解。在50 mM HCO3−的存在下，铜催化的类fenton反应([Cu(II)]0 = 0.1 mM， [H2O2]0 = 10 mM, pH = 10)对苯酚的降解速度提高了17倍。Cu(II)/HCO3−/H2O2体系对苯酚的降解速率随Cu(II)和HCO3−浓度的增加而增加，但在H2O2浓度和pH分别为5 mM和10 mM时达到最佳值。Cu(II)/HCO3−/H2O2体系对酚类化合物有选择性降解;苯甲酸不易降解。Cu(III)物种(可能与碳酸盐络合形式)被认为是Cu(II)/HCO3−/H2O2系统降解苯酚的活性氧化剂。同时，通过铜催化的类fenton反应，曝气CO2气体成功地加速了苯酚的降解，这意味着在实施Cu(II)/HCO3−/H2O2体系时，CO2曝气可以作为一种实用的选择来供应碳酸氢盐。
