The detection limits of iodide, glyphosate, perchlorate, bromide were 0.002 mg/L, 0.005 mg/L, 0.001 mg/L and 0.004 mg/L, respectively, and those of other five compounds met the requirements of relevant standards. At the quantitative limit level，the average recoveries were 96.3%-104% and the relative standard deviations were 0.68%-3.79%. The method is simple and sensitive, and can be applied to analyze drinking water and source water efficiently. The method was applied to detect the relevant indexes of source water in a city in south China. Iodide and bromide were widely detected in the source water with average concentrations of 0.028 mg/L and 0.037 mg/L, respectively, and high iodine concentration was detected in particular reservoir. Perchlorate and glyphosate were not detected. Fluoride, chloride, nitrate nitrogen, sulfate and other indicators met the limitations specified in surface water class Ⅱ standard. Water samples from 50 waterworks were tested. Iodide, perchlorate, glyphosate, bromide and phosphate were not detected, and other indicators met the requirements specified in drinking water quality standard. It is suggested to pay attention to the risk of iodine and bromine disinfection byproducts in water supply process.类似文献/References:[1]李秀虹,刘则华,林青,等.中日两国自来水水质的主要影响身分周全对照阐发[J].中国给水排水,2018,34(20):24.
