摘要
在使用南非钴精矿进行冶炼过程中,水相和有机相中间有层难以分相的乳化层,通过红外光谱和气相色谱—质谱联用技术对其结构分析,发现其主要结构与腐植酸结构相似。采用测定有机碳,间接求出腐植酸的质量分数,方法的回收率达到99.94%。
There is the emulsion layer between aqueous and Organic phase in smelting process of using cobalt concentrate of South Afirica. The structure of emulsing layer and humic acid are alike by infrared spectrum and gas chromatograghy - mass spectrometry analysis. The organic carbon is determined in the smaple and huraic acid content is indirectly calculated. The recovery rate can reach 99. 94%.
