摘　　要：本文用超滤膜方法证实氯酚与富里酸之间存在缔合作用,并计算出表观缔合常数(K)在2.7×10~3—121×10~3ml·g^(-1)范围内 实验结果表明:pH、富里酸含量、氯酚取代氯原子个数都能够影响K值的大小.There is an association between fulvic acid and chlorophenols, which is verified by the ultrafiltration membrane method in this article. The apparent associated constant K is calculated is from 2.7×103to 121×103ml·g-1. The experimental results show that pH, the content of FA and the number of Cl atom in the benzene ring of chlorophenol can affect the apparent associated constant K.
