摘要
研究了用ICP -AES法同时测定磷矿石中氧化铁和氧化铝。考察了谱线的选择、基体的影响。方法回收率为 94.8%～ 1 0 3.6 % ,精密度为 2 .1 0 %～ 3.0 2 %。
A method for simultaneous determination of iron oxide and alumina in phosphorus rock by using ICP-AES is studied in this paper.Selection of analytical wavelength and effect of matrix element are studied.The recovery for this method is in the range of 94.8%～103.6%,and the relative standard deviation(RSD) is in the range of 2.10%～3.02%.
