| 摘 要： | 研究了采用CCD-ICP-AES同时测定化肥中As、Cd、Co、Cr、Cu、Hg、Mo、Ni、Pb、Sb、Se和Zn等12种有害元素的方法.采用微波消解法处理样品,加入Y作为内标,消除了化肥基体对测定结果的干扰效应.方法对化肥中各元素的测定回收率在81.6%～120%之间,测定精密度在0.7%～13.8%之间.用该法测定了两种国家标准物质.

| Abstract: | A method for simultaneous determination of As, Cd, Co, Cr, Cu, Hg, Mo, Ni, Pb, Sb, Se and Zn in fertilizer by CCD-ICP-AES was presented. Microwave digestion was used for sample preparation. The interference effect of matrix was observed but effectively corrected by Yttrium internal standard method. The recoveries of elements in fertilizer were in the range of 81.6% - 120%, with 0.7% - 13.8% RSD. Testing results of two certified reference materials were satisfactory. |
