摘要
Abstract
By adopting nitric acid digestion water sample, the method of direct determination of cadmium in water samples by flame atomic absorption spectrometry was established . The method of dissolving samples and matrix in-terference were discussed. The results showed that under selected experimental conditions, the matrix interference did not interference the determination of cadmium. The linear range was 0. 05~1mg/L, the detection limit was 0. 011 mg/L. This method was applied to analyse real samples, the relative standard deviation was below 1%, the re-covery rate was 98% ~102%.关键词
