Influence of Different Matrix Modifiers on Determination of Pb in Powder Cosmetics

LI Hui-yon

Abstract

The determining method of Pb in powder cosmetics by graphite furnace atomic absorption spectrometry(GFAAS) was studied.The influence of different matrix modifiers on this determination was emphasized studied.When 0.25%(NH4)H2PO4 was used as matrix modifier,the stability and sensitivity of the determination of Pb in powder cosmetics were effectively improved.
