根据地质普查和综合研究的需要,我们试验了硫化物中铜、钴、镍物相分析的化学分析法。国外,有用抗坏血酸和过氧化氢混合溶剂浸取硫化物中的铜、钴、镍,并用原子吸收光谱法测定。此法费时冗长,仅浸取就需12小时以上,成本又较高,不能满足野外分析的要求。我们参考了国内外有关资料,采用了含有浓溴的饱和溴水浸取硫化物形式存在的铜、钴、镍,并经试验确定:0.5克试样以2毫升饱和溴水和5滴浓溴,浸取半小时即可,然后根据不同要求选用下列方法之一
According to geological survey and comprehensive research needs, we tested the chemical analysis of copper, cobalt, nickel phase analysis of sulfide. Abroad, ascorbic acid and hydrogen peroxide mixed solvent leaching of sulfide copper, cobalt, nickel, and atomic absorption spectrometry. This method is time-consuming and time-consuming, only leaching requires more than 12 hours, the cost is higher, can not meet the requirements of field analysis. We refer to the relevant information at home and abroad, the use of saturated bromine containing concentrated bromine in the form of sulfide sulfide sulfide, cobalt and nickel, and determined by experiments: 0.5 g sample with 2 ml of saturated bromine and 5 drops of concentrated bromine , Leaching for half an hour, and then choose one of the following methods according to different requirements
