摘要
依据草酸钴产品中Co2+∶C2O42-为1∶1,以测定C2O42-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%。
According to that Co^2＋：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 range tested：≥ 31%,difference：〈0.2%.
