| Abstract: | With the microwave digestion technique and graphite furnace atomic absorption spectrometry method, the trace cadmium in water treatment reagent is measured. The linear range is 0~20μg/L, the detection limit is 0.13μg/L, the relative standard deviation is 2.6%, and the recovery is 98.0%. The proposed method is proved to be accurate, rapid and convenient. It has been used in the determination of water treatment reagent. |
