测定了几种酚类的分解反应速率常数，双酚A、对氯苯酚、对辛基苯酚、2，4-二氯苯酚、对叔丁基苯酚以及废油中的二苯甲酮和多氯联苯化合物。采用了以下方法：电解、光解、声解、光解电解和声解电解。初始浓度固定为50毫克/升，但多氯联苯除外，其所有异构体的浓度均为500纳克/升。溶剂是水，但对于溶解度不足的化学品，使用与醇的混合物。超声的额外应用导致对氯苯酚和2，4-二氯苯酚的显着增强。多氯联苯化合物的电解速率常数与苯酚的电解速率常数相当。二苯甲酮的分解速度是酚类的10倍，部分原因是溶剂中含有醇类。
Rate constants for decomposition reaction were measured for several phenols, i.e., bisphenol A, p-chlorophenol, p-octylphenol, 2,4-dichlorophenol, p-tert-butylphenol and for two other chemicals, benzophenone and PCB compounds in waste oil. The following methods were adopted: electrolysis, photolysis, sonolysis, photolytic electrolysis, and sonolytic electrolysis. The initial concentration was fixed at 50 mg/L except for the PCB, for which the concentration for all the isomers was 500 ng/L. The solvent was water, but for chemicals with insufficient solubility, mixtures with alcohols were used. Additional application of ultrasound led to remarkable enhancement for p-chlorophenol and 2,4-dichlorophenol. The electrolysis rate constant for PCB compounds was comparable to that for the phenols. Benzophenone was decomposed 10 times as slow as the phenols partly because of the solvent containing alcohols.
