| Abstract: | A sample of cream cosmetic was pretreated with three different digestion methods for comparison.namely,HNO 3-H 2SO 4-HClO 4 digestion,HNO 3-H 2SO 4 digestion,and mixed(HNO 3 HClO 4)-H 2SO 4 digestion,with its Cu,Cr,Cd,Mn,Zn and Pb concentrations determined directly by ICP-AES.It has been found that the best pretreatment method is the mixed (HNO 3 HClO 4)-H 2SO 4 digestion,with its indexed recovery rate at 93 6%-103 8% and its relative standard deviation (RSD) for 10 times lower than 4 89%.The method is rapid,accurate and easy to operate. |
