摘要
研究了测定铜冶炼烟尘中铋含量的Na2EDTA络合滴定方法。对测定体系中的各干扰元素进行了研究,探讨了测定方法的各项测定条件。方法的相对标准偏差为0.40%~0.67%,样品加标回收率在99.9%~100%,方法精密度高,准确度好。适用于铜冶炼烟尘中铋含量为5.00%~16.00%的测定。
The Na 2EDTA complexometric titration method for the determination of bismuth content in copper smelting dust was studied.The interfering elements in the determination system were studied experimentally.The determination conditions of the method were discussed.The relative standard deviation of the method is 0.40%-0.67%,and the recovery of the sample is 99.9%-100%.The method has high precision and accuracy.It is suitable for the determination of bismuth content in copper smelting dust from 5.00% to 16.00%.
