摘要：

为减小饮用水在氯消毒过程中产生的消毒副产物所带来的危害,采用铁刨花去除饮用水中低质量浓度的三氯硝基甲烷（TCNM）,考察了其在不同反应条件下对TCNM的去除效果及其影响因素,并探讨了其降解机理及动力学规律.结果表明：铁刨花对低质量浓度的三氯硝基甲烷有较好的去除效果,对于100 mL、质量浓度为5 μg/L的三氯硝基甲烷溶液,当铁刨花的投加量为4 g时,反应180 min后,去除率达到90.15％,随着铁刨花投加量的增加,三氯硝基甲烷的去除率增加,铁刨花投加量对三氯硝基甲烷的去除效果影响较大.在低浓度的三氯硝基甲烷条件下,三氯硝基甲烷初始浓度的变化对去除三氯硝基甲烷的去除效果影响不大.铁刨花还原去除三氯硝基甲烷的反应符合一级反应动力学规律.
Abstract:

Iron scraps was applied to remove the trichloronitromethane (TCNM) in order to reduce the risk of disinfection by-products (DBPs) from chlorination process in drinking water. The TCNM removal efficiency and it's influencing factors were investigated in different reaction conditions. The mechanism of degradation and kinetics were also explored. The results indicated that TCNM in low concentration could be well removed by iron scraps， and when the TCNM solution was 100 mL with the initial concentration of 5 μg/L, the removal efficiency could reach to 90.15% after 180 min with the addition of iron scraps of 4 g. The addition of iron scraps was of great impact on the TCNM removal and the removal efficiency increased with the increase of iron scraps addition. However, the TCNM removal efficiency did not change a lot with the variation of the initial TCNM concentration when it was in a low level. The TCNM reduction by iron scraps followed the first-order kinetic model.
