摘要
Abstract
A method was developed for the determination of Pb,Cd,and As in standard materials of Cabbage by inductively coupled plasma mass spectrometry(ICP-MS).After the two pretreatment methods of wet digestion and microwave digestion,the samples were directly determined by ICP-MS with on-line interna1 standard to correct the the instrument signal drift.Comparig determination results on elements of Pb,Cd,As determinated by two pretreatment methods,their detemination value has no significant difference with the reference value range.The relative standard deviation is between 0.41-4.0%,the result is accurate and reliable.Two pretreatment methods all can be used as ICP-MS pretreatment methods.关键词
