| Abstract: | In this paper, a method of microwave digestion followed by cold atomic absorption spectrometry for the determination of mercury in cosmetics was developed. Microwave digestion conditions and operational conditions of cold atomic absorption spectrometry were optimized. The characteristic concentration is 0.000 25g/mL ,the RSD is 2.01%, the recovery is from 98% to 102%. The method is simple,fast and accurate, the result is satisfied. |
