摘要
本工作通过选择性化学溶解将地质样品分成了六个相:碳酸盐、金属相、硫化物、氧化物、硅酸盐以及不溶性残渣。这一流程的建立不仅考虑了一系列实验参数,如:溶剂种类,溶解各相的时间、温度及pH值等,而且还考虑了铱在各相溶解中状态的变化。整个流程对相分离的误差可以满足中子活化对地质样品分析的要求。
A new selective chemical dissolution procedure was developed in which a geological sample was separated into six components, i. e. carbonate, metal, sulfide, oxide, silicate and HF-insoluble residue. The experimental parameters, including the reagent types, temperature and digestion time, and the acidity during the dissolution of different phases were investigated. In the established method, the chemical state of other phases generally did not affect the dissolution of the phases of interest.
Some practical samples were analyzed by the procedure.
