| 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. |
