| Abstract: | Inductively coupled plasma mass spectrometry （ICP-MS） determination of lead and cadmium in the drinking water at the same time, to establish a simple, sensitive and accurate method for determination of drinking water. The experiments show that the method of the wide range of linear, linear correlation coefficients were：〉0.999, recycling price table of the elements are in the range of 97.2 % to 106.8 %, the relative standard deviation of 1.7 %. Determination of quality control samples were in the range of the method is simple, fast, sensitive, accurate and suitable for the heavy metals lead, cadmium in drinking water. |
