| Abstract: | We studied a new method to determine the trace cadmium,copper and lead in drinking water by concentration with hydrosulfurlyl cotton and AAS.In our experimental condition.the linear range of cadmium and copper are 0 004～0 040 μg/ml,lead is 0 1～1 0 μg/ml;the correlation coefficient of cadmium 0 9991,copper 0 9996,lead 0 9999;recorery of cadmium 96 9～105 0%,copper 98 09～101 3%,Lead 100 00～101 00%;variation coefficient of cadmium 3 5%,copper 1 76%,lead 5 25%. |
