微波消解-ICP-AES法测定化妆品中无机元素的研究Ⅰ.固体类化妆品中As,Pb,Cd,Sr,Cr,Bi和Se等的分析方法研究

Study on the Elements in Cosmetics by Microwave Digestion ICP AES Ⅰ The Determination of Pb,As,Cr,Cd,Sr,Bi and Se in Solid State Cosmetics

本文用国产微波消解系统，研究了安全地，有效地消化固体类化妆品最佳酸体系，以及消解罐内压力，微波功率和消化时间等参数并研究了固体类化妆品中一些无机元素的分析方法，即溶样后用ＩＣＰ－ＡＥＳ法测定砷，铅，镉，铬，锶，铋，硒元素的含量。用该法测定化妆品国家一级标样相对误差０．７４％。

A safe and effective method for the microwave digestion of solid state cosmetic samples is described.The overall digestion conditions,including pressure,power,acids and time of digestion were evaluated by analysing Pb,As,Cr,Cd,Sr,Bi and Se of routine samples with ICP AES.This method was applied to the determination of certified materials with good agreement.
