摘要: 水解是有机污染物转化降解的重要途径.天然水体中的腐殖质影响有机化合物的水解速度常数,使之与蒸馏水缓冲系统中的测定值有较大差别.本文推导并验证了腐殖质浓度与水解速度常数的定量关系,测定了腐殖质与有机化合物的缔合系数.

Abstract: Quantitative relationship between rate constants k for hydrolysis of organic pollutants and the concentrations of humic substances, k = k'/(1 + AM) , was proposed.The relationship was verified by three esters.Association coefficient Aderived from the method of Sep Pak column agrees with that derived from the method of hydrolysis well.

Key words: Hydrolysis, Humic substances, Methyl Acetates
