| Abstract: | A new method has been developed for the determination of Pb,Cr and Cd in mill scale by inductively coupled plasma-atomic emission spectrometry（ICP-AES）.The samples were digested by HCl（1＋1）and determined by ICP-AES with with matrix matching.The detection limits of the method for Pb,Cr and Cd were 0.0008%,0.00012% and 0.00008%,respectively,and the maxium RSD was 8.33%,and the recovery of the method was in the range of 92.0% to 110%. |
