| Abstract: | It masks interfering ions through adding several masking agents,and achieves rapid titration of lead EDTA in battery.Experimental results show that improved titration has characteristics as follows: changing in titration end-jump obviously,high precisions,good reproducibility,low cost,fast and simple advantages.Titration error is less than 0.40 % and meet ing the high-grade lead chemical analysis of error requirement. |
