Influences of humic acids on the catalytic oxidation of tetrabromobisphenol A (TBBPA) using iron(III)-porphyrin catalysts were investigated. The TBBPA was difficult to be oxidized and dehalogenated by the catalysts, compared to chlorinated phenols that had been investigated. In the catalytic oxidation of TBBPA, oxidative coupling reactions that can produce the oligomers were dominant. In the presence of humic acids, coupling compounds between oxidation intermediates from TBBPA and humic acid were mainly formed, and percents conversion of TBBPA to the coupling compounds were from 50 to 60%. The toxicity tests of the reaction mixtures in the absence and presence of humic acids by the inhibition of an algae (P.subcapitata) growth demonstrated that toxicity of TBBPA was reduced in the presence of humic acids.

研究了腐殖酸对铁卟啉催化氧化四溴双酚A（TBBPA）的影响。与已研究的氯代酚相比，TBBPA很难被催化剂氧化和脱卤。在TBBPA的催化氧化反应中，氧化偶联反应是主要的反应，可以产生低聚物。在腐殖酸存在下，TBBPA氧化中间产物与腐殖酸主要形成偶联物，TBBPA转化为偶联物的转化率为50 ~ 60%。在腐殖酸存在和不存在下的反应混合物的毒性测试通过抑制藻类（P.subcapitata）生长证明，在腐殖酸存在下TBBPA的毒性降低。
