摘要： 考察了溶液pH值、光催化剂质量浓度、腐殖酸初始浓度等因素对腐殖酸去除的影响，运用SEC和LC-OCD联合分析降解过程中腐殖酸分子变化情况并模拟饮用水的消毒过程.结果表明，降解是一个由腐殖酸大分子到小分子酸的过程，光催化体系不但能使腐殖酸褪色，还大大降低了消毒副产物生成势.

Abstract: This study investigated the effects of different factors on removal of Humic Acid(HA), such as initial pH, mass concentration of catalyst, initial mass of HA, etc. The combination of SEC and LC-OCD analysis showed that the large HA molecular was converted into acids of small molecular gradually during degradation process. By simulating the disinfection process, the paper demonstrated the photo-catalytic system could not only remove the color of HA but also diminish the formation potential of DBPs effectively.
