摘　　要：用超滤技术将水样中的有机物按分子量分段 ,测定了不同分子量段水样中的总有机碳含量和经氯代反应后的水样中三氯甲烷的含量 ,评价了影响有机物卤代活性的因素 .结果表明 ,水中不同分子量段的有机物含量的分布与水体污染程度有关 。Organics in natural water is separated into different parts of molecular weighted by the ultrafiltration. C TOC in all samples with different molecular weights are determined and CHCI 3 in samples of halogenation are also determined. The halogenation activity of each part of the organics is evaluated. The results show that the molecular weight distribution in different parts of samples are close related to the degree of pollution of water body. The halogenation activity is different for the organics with different molecular weights.
