摘　　要：本研究以典型氨基糖类物质D-(+)-葡萄糖胺为研究对象,采用氯消毒方式,探究了D-(+)-葡萄糖胺是否是卤代碳、氮消毒副产物三卤甲烷(THMs)和三氯硝基甲烷(TCNM)的前驱物,明确其THMs和TCNM生成势及投氯量、p H值、溴离子浓度、亚硝酸根离子浓度这对其生成势的影响。结果表明:D-(+)-葡萄糖胺是THMs和TCNM的主要前驱物,三氯甲烷是氯消毒过程中主要的THMs物种。增大投氯量,HNMs和TCNM的生成势均升高;随着p H值的增大,THMs的生成势升高,TCNM的生成势先升高后降低;随着溴离子浓度和亚硝酸根离子浓度的增大,THMs的生成势均为先升高后降低,而TCNM生成势在高溴离子和高亚硝酸根离子浓度下则表现出被抑制的趋势。The paper took typical amino sugars D - （ ＋ ） - glucose amine as the research object,used the chlorine disinfection to explore whether the D - （ ＋ ） - glucosamine is the precursor of halogenated carbon and nitrogenous disinfection byproducts trihalogenated methane （THMs） and trichloronitromethane （ TCNM）, and cleared the formation potential of THMs and tcnm and studied the influence of adding amount of chlorine, pH value, the concentration of bromide ion, nitrate ion concentration on the formation potential. The results show that the D - （ ＋ ） - glucosamine is the main precursors of THMs and THMs. Chloroform is the major THMs species in the process of chlorine disinfection. To Increase the investment, the generating potential of TCNM and HNMs will increase;with the increase of pH, formation potentiall, the formation potential of THMs will first increase and then decrease ; with the increase of concentration of bromide ion and nitrite ion, the formation potential of THMs will first increase and then decrease. The formation potential of THMs under the concentration of high bromine ion and high sub nitrate ion showed suppressed trend.
