草酸钴中钴的快速测定—电位滴定法

Rapid Test of Co Element in Cobalt Oxalate by Potential Titration Method

摘要: 依据草酸钴产品中Co²⁺ :C₂O₄^2-为1:1，以测定C₂O₄^2-的量而间接测定钴的含量，钴和共存杂质元素几乎不干扰测定，钴的测定范围：≥31%，误差 < 0.2%。

Abstract: According to that Co²⁺:C₂O₄^2- in Cobalt oxalate products is 1:1, indirect test of C₂O₄^2- content could calculate Co. Co and inpurity elements do not interfere test. This method is simple, sensible, rapid and accurate. Co ran ge tested:≥31%, difference: < 0.2%
