氢化物发生-非色散原子荧光光谱法测定粉饼化妆品中Pb,As和Hg含量
Determination of Pb,As and Hg contents in powder cosmetics by hydride generation-non-dispersive atomic fluorescence spectrometry
摘要
Abstract
This study established and optimized a method for the determination of lead(Pb),arsenic(As)and mercury(Hg)in 10 powder cosmetics using hydride generation-non-dispersive atomic fluorescence spectrometry(HG-NDAFS).This study determines that the optimal carrier gas flow rate is 400 mL/min and the optimal shielding gas flow rate is 800 mL/min.The negative high voltage and lamp current are optimized,and the atomizer height is determined to be 8 mm.When optimizing the reductant system,1.5%is selected as the best KBH4 solution.The carrying current is 2.4 mol/L HCl.The standard recovery rates of Pb,As,and Hg are 83.44%-90.32%,83.22%-86.59%,81.43%-89.94%respectively.The standard recovery rates are good.Among the 10 types of pressed powder,2 types of pressed powder are detected to contain Pb(0.48 and 0.27 mg/kg),1 type of pressed powder contained As(0.62 mg/kg),and 1 type of pressed powder contained Hg(0.11 mg/kg).The contents of Pb,As,and Hg in the 10 kinds of powder cosmetics do not exceed the standard.In a word,the HG-NDAFS method established in this study for the determination of Pb,As and Hg in powder cosmetics is accurate and can be used for the determination of Pb,As and Hg in powder cosmetics.关键词
