| 中文摘要: |
| THMs和HAAs为饮用水中两大类主要的氯消毒副产物(ICDBPs)．THMs和HAAs中的THAA(或X3AA)的生成途径相类似，当水中含有Br—时会形成含Br的THMs和X3AA，且Br离子浓度对两种组成成分的影响也很相似．据此特点，建立了一种用各种THMs和Cl3AA的摩尔浓度来预测相应的其他三种X3从浓度的模型，并用实验数据进行了验证。 |
| 英文摘要: |
| Trihalomethanes(THMs) and haloacetic acids (HAAs)are two significant groups of chlorination disinfecting by-products(CDBP_s). THMs and trihaloacetic acids(THAA or X_3AA) have the similar formatiom pathways. Chlorination of bromide containing waters can form bromo- species of THMs and THAA,and the bromide ion concentration affects their species distribution in similar way. According to these,a model untilizing the molar concentrations of four THM and trichloroacetic acid to predict corresponding remaining trihalocetic acids was developed,and some experimental results were cited to examine it. |
