| 摘 要： | 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）氯化后氯信形成的规律与氯化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ＴＨＭｓ前体。

| Abstract: | ased on our
experiments,it was proved that Humic Acid (HA)wasable to be used as the trihalomethanes
precursors(THMP)in natural Waters,resorcinol(with one active carbon site),phloroglucinol(with
three activecarbon sites) and compounds with the structure of methyl ketone-pyruvatefailed to
represent the active coinpositions of HA. However,the complex ofresorcinol with pyruvate(1:4
W/W)reflected the character of HA well,and can be used as the active compositions in HA. |
