摘要
王水溶样,氢溴酸除锡,直接用EDTA容量法测定铅阳极泥中高含量的铋。结果与用pH试纸控制滴定体系酸度的经典测铋方法结果相一致,RSD(n=4)<1%。
The samples were dissolved in HCl+HNO_(3) (1∶3) and hydrobromic acid were added in order to eliminate the interference from tin. Then bismuth in lead anode mud was determined by EDTA complexometric titration. The results are in agreement with those provided by the classical method with precision of <1% RSD (n=4).
