%X The kinetics of endocrine disruptor 4-tert-butylphenol by chlorination in aqua was studied. The results showed that 4-TBP was rapidly oxidized by chlorine with different initial concentrations of HOCl and pH, and second-order reaction kinetics was observed between 4-TBP and chlorine. The apparent kinetic rate constants were influenced by pH values, kapp reached its highest and lowest level at pH 5 and 9 respectively. The kinetic rate constant of every elementary reaction was calculated. The rate constants for the acid-catalyzed reaction and the reaction between between ClO- and4-TBP were 4.99×106 L2?mol-2?s-1 and 1.96×104L?(mol?s)-1 respectively. The reaction between HOCl and 4-TBP or HOCl and 4-TBP- was very slow, and ClO- did not react with 4-TBP-. 4-TBP was influenced by chlorine disinfection during water treatment. The corresponding half-life times was 12.1min when chlorine concentration was 3 mg/L.
