| Abstract: | s:The sewage sample was digested with nitric acid-perchloric acid, the cadmium in which was determined by flame emission atomic absorption spectrometry. Under the optimum experimental conditions, the linear range of the method was 0~1.0 mg/L, the detection limit was 0.05 mg/L, the relative standard deviation was less than 2.58% and the recovery was 97%~102.0%. |
