EDTA滴定法快速测定硅钡合金、硅铝合金、硅铝钡钙合金、硅钡铝合金中铝的质量分数

QUICKLY DETERMINING ALUMINIUM CONTENTS OF Si-Ba ALLOY,Si-Al ALLOY,Si-Ba-Al-Ca ALLOY AND Si-Ba-Al ALLOY WITH EDTA VOLUMETRICMETHOD

相比于氟盐置换EDTA滴定法,硝酸铋回滴过量EDTA法快速测定硅钡合金、硅铝合金、硅铝钡钙合金和硅钡铝合金中的铝含量,操作简便、快捷,成本低,结果准确稳定。

The method of using bismuth nitrate back titrating excessive EDTA solution is introduced to determine of Si-Ba alloy, Si-Al alloy, Si-Al-Ba-Ca alloy and Si-Ba-Al alloy. Comparing to the titration method of EDTA replaced by villiaumite, it has many advantages, such as simple and fast procedure , low cost and the accurate result.
