Simultaneous Determination of Hg As Pb in Cosmetic Products by ICP-AES
Sample was digested in polytetrafluorethylene sealed vesssle by nitric acid-perhydrol or high chloric acid-perhydrol, Hg As Pb were simultaneously determinated by ICP-AES. The recoveries were 86.0%, 96.2%, 99.8% and the relative standard deviation were 3.17%, 2.51%, 2.01%. The results between AAS and ICP-AES has no significant difference.
