短碘量法测定高镁铜精矿铜量分析方法的优化

Optimization of the Method for Determination of Copper Content in High-magnesium Copper Concentrate by Short-iodine Method

对国标短碘量法测定高镁铜精矿铜量[1]加以优化,进行了镁干扰实验、样品返色实验及与经典法国标长碘量法进行结果对照,准确度、精密度、加标回收率实验等,判断分析方法的可行性。方法操作简便,精密度好、准确度高。测定范围:含镁量:10.00%~25.00%。

The copper content[1]of the high-magnesium copper concentrate was optimized by the national standard short-iodine method.We carried out the magnesium interference experiment,the sample back-to-color experiment,the comparison with the classical French standard long-iodine method,the experiments of accuracy,precision and addition standard recovery rate were carried out to judge the feasibility of the analytical method.The method has the advantages of simple and convenient operation,good precision and high accuracy.Measurement range:magnesium content:10.00%~25.00%.
