通过实验证实，可用腐植酸（ＨＡ）代表天然水中三卤甲烷（ＴＨＭｓ）的前体。单一模拟化合物（含一个活性空位碳原子的间苯二酚，三个活性空位碳原子的间苯三酚，及甲基酮类化合物的丙酮酸钠）氯化后氯仿形成的规律与氯化ＨＡ的不一致。而间苯二酚与丙酮酸钠的混合物（１：４Ｗ／Ｗ）能很好地反映出ＨＡ中活性结构的特性。为今后研究ＴＨＭｓ的形成提供了一个可资定量比较的ＴＮＭｓ前体。
It has been experimentally demonstrated that humic acid (HA) can be used to represent the precursors of trihalomethanes (THMs) in natural water. The formation of chloroform after single simulated compound (resorcinol containing one active vacancy carbon atom, phloroglucinol with three active vacancy carbon atoms and sodium pyruvate of methyl ketone) after chlorination was similar to that of chlorinated HA Inconsistent. The mixture of resorcinol and sodium pyruvate (1: 4 W / W) can well reflect the characteristics of the active structure in HA. For the future study of the formation of THMs provide a quantitative comparison of TNMs precursors.
