Studying on some plant cobalt aqueous phase, it carried out high-purity cobalt oxide or cobaltoxalate preparation tests in the laboratory.
以某厂含钴水相为研究对象，在实验室开展了高纯氧化钴或草酸钴的制备试验。
2
Study is made of a new process for directly extraction of the cobaltoxalate from ammonium oxalate in the acid solution directly dissolved from lithium cobaltate.
目的：探讨采用草酸铵作为提取溶剂和超声波振荡处理法提取菠萝皮渣果胶的工艺条件。
3
The influences of vacuum decomposition conditions (temperature, time and particle size of cobaltoxalate) on the particle size and oxygen content of cobalt powder were tested.
