前言氧化钴为钴的冶炼中间产品。对钴、锰、镍三元素分析,通常分样测定:用亚硝酸钴钠沉淀分离EDTA容量法测钴;硫酸亚铁铵容量法测锰:有机溶剂萃取分离丁二酮肟比色法测镍.不但操作繁琐,试剂多,流程长,且易带来误差,也不适应冶金过程中控制分析。过去分析钴,沉淀老化12小时以上。锰在氧化钴中,含量在0.05%～1.0%左右,一股较低,容量法不适宜。为适应氧化钴冶炼控制分析,经过试验整理氧化钴中钴、锰、镍的连续测定系统分析方法,经生产检验,已见成效。
Preface Cobalt oxide is a cobalt smelter intermediate. For cobalt, manganese, nickel three elemental analysis, usually subsample determination: precipitation of cobaltous acid with sodium nitrite EDTA volumetric method for the determination of cobalt; ammonium ferrous sulfate volumetric method for the determination of manganese: organic solvent extraction dimethylglyoxime colorimetric determination of nickel Not only cumbersome operation, reagents, long process, and easy to bring error, also do not meet the metallurgical process control analysis. In the past analysis of cobalt, precipitation aging for more than 12 hours. Manganese in cobalt oxide, the content of about 0.05% to 1.0%, a lower, the volume method is not appropriate. In order to meet the control analysis of cobalt oxide smelting, through the test finishing cobalt oxide, manganese, nickel continuous determination system analysis method, the production test, has achieved results.
