摘要
提出了用NaOH熔融生料样品 ,EDTA滴定法测定其CaO含量的方法。该方法测定结果准确、快速 ,回收率为97 2 5 %～ 10 5 % ,相对标准偏差 (RSD)小于 2 0 3 %。完全能满足生料样品的分析要求。
A method for the determination of calcium oxide in raw material was presented.The sample was melted by sodium hydroxide,and titrated by EDTA.The method was accurate,rapid and convenient.The recoveries ranged from 97.25% to 105%.Relative standard deviation was less than 2.03%.The proposed method has been applied to analysis of raw material with satisfactory results.
