摘要
建立了电感耦合等离子体原子发射光谱法测定氧化铁皮中铅、铬、镉的新方法。样品采用盐酸分解,以高纯铁进行基体匹配。铅、铬、镉的检出限分别0.0008%、0.00012%、0.00008%,最大相对标准偏差为8.33%,方法回收率介于92.0%-110%之间。
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%.
