摘　　要：采用了铅试金法富集与分离、DDO法测定高冰镍试样中铂和钯。对试金配料进行了研究,以碱性配料硅酸度控制在0.5为宜;再用DDO法测定高冰镍中的铂和钯。该法分析准确性好,相对标准偏差小于3.3%,方法回收率98%以上。The experiment adopts the enrichment and separation method of Pb-assaying.The DDO method is used to determine platinum and palladium simultaneously in High-grade nickel matte. Through researching the component of assaying,an appropriate make-up is put forward with the silicic acidity of 0.5. The method provides a high accuracy.The RSD is found to be less than 3.3% and recoveries are more than 98%.
