微波消解ICP-MS同时测定色母粒中多种重金属元素

摘要

采用微波消解-电感耦合等离子体质谱（ICP-MS）法对色母粒中的铅、砷、铜、镉等重金属元素的含量进行了测定,方法快速准确、灵敏度高,加标回收率在96.0%～106.0%,相对标准偏差〈3%。%A method for the simultaneous determination of Pb,As,Cu,Cd in master batch by ICP-MS microwave digestion was studied.This method has simple operation,rapid analysis,highly accurate,reliable,and can be applied in simultaneous determination of heavy metal elements in master batch.Recoveries of the elements from the spiked master batch sample were in the range of 95.2%~101.8%,and the RSD was less than 3%.The results obtained agreed quite well with the certified values.
