本方法的是为解决从玻璃纤维行业含铂铑废耐火砖中回收的铂铑合金及钝铂铑合金材料中杂质元素的分析而建立的。铂铑系二元合金中杂质元系的光谱分析在国内未见报导。贵金属研究所曾作了铂—钯_3—铑_4[1]三元素合金中的杂质测定。由于我们生产中铑的含量不固定,一般低于10%。 The method was developed to solve the analysis of the impurity elements in the platinum-rhodium alloy recovered from the platinum-containing rhodium-containing refractory bricks in the glass fiber industry and the platinum-rhodium alloy material. The spectral analysis of impurity elements in platinum-rhodium binary alloys has not been reported in China. The Institute of Precious Metals has made the determination of impurities in platinum-palladium-3-rhodium-4 [1] ternary alloys. Due to the fact that the content of rhodium in our production is not fixed, generally less than 10%.
