用火试金法富集贵金属溶液中的金和钯

Concentration of the golden and palladium element in precious metals solution with fire-assaying method

将经浓缩的小体积的贵金属溶液直接加入到火试金配料中，用火试金方法分离贵金属元素中的金和钯及其它杂质元素．实验结果表明，该方法的分析结果与经典的活性炭吸附方法相符，相对标准偏差为1．02％～10．9％（n=6）．

Little volume of precious metals solution could be direct injected into the batching of fire-assaying, and the elements of the gold and palladium could be separated from the impurity elements by the method of fire-assay- ing. The gold analytical results using this method corresponded with the results of classical method.The relative stan- dard deviation was 1.02%- 10.9% （ n=6 ）.
