ICP-MS法快速测定丙烯腈/乙腈中的铁、铜

Rapid Determination of the Ferrum and Copper in Acrylonitrile and Acetonitrile by ICP-MS

摘要: 采用带八级杆碰撞/反应池(ORS)的电感耦合等离子体质谱法(ICP-MS),直接测定丙烯腈或乙腈产品中的Fe、Cu,标准加入法定量.结果表明,方法的线性范围宽,线性相关系数均大于0.999.2种元素的相对标准偏差均低于5%,加标回收率在90%~110%.该方法简便、快速、准确.

Abstract: Rapid determination of the Fe and Cu in acrylonitrile and acetonitrile by ICP-MS with ORS by standard addition was reported.As a result,the linearity of this method is very wide,and the relate coefficient of linearity is more than 0.999.The relate standard deviation of two elements is less than 5%,recovery efficiencies of standard addition vary from 90% to 110%.This method is safety,simple,rapid and accurate.
