Abstract: Nine metal elements,i.e.,Co,Mn,Pb,Ca,Zn,V,Zr,La and Ce,in various driers were determined by ICP-AES.The drier sample was digested with conc.HNO3 and HClO4 in a closed PTFE vessel under pressure and heated by microwave in 2 steps.The solution obtained was diluted to a definite volume and used for ICP-AES analysis.Simultaneous determination of the 9 elements was achieved by choosing appropriate analytical spectral lines.Standard working curves were prepared by using mixed standard solution,giving ranges of linearity between values within 100.0 mg·L-1 for all these elements.On the base of a drier sample,test for recovery was made by addition of standard solution,and the values of recovery found were in the range of 93.8%-109.9%,with values of RSD′s (n=6) ranged from 0.11% to 1.56%.As shown by the results of analysis of 5 driers from various sources,kinds and contents of metal elements found were quite different.It was also proved that the proposed method is rapid,convenient and easy in operation and is feasible for routine analysis.
