| Abstract: | An analytical method of the determination of arsenic and lead in cosmetic by GFAAS has been studied. The sample preparation can be easily accomplished by using a wet-digestion procedure and this is easy to master. The determination sensitivity is enhanced.The limit of detection of lead is 0. 010 ng and that of arsenic 0. 013ng. The recovery rates of the method is 96.1% -105. 8%. The relative standard deviation fell into 0. 8%-5. 2%. |
