摘　　要：　对分解后的矿样采用α-糠偶酰二肟萃取分离出钯,并用I2-CCl4萃取分光光度法测定金,再用三壬胺-二甲苯溶液和氢氧化钠溶液萃取和反萃取分离出铂,采用I2-CCl4萃取分光光度法测定铂。通过方法的回收率试验测定金的回收率为94%～104%,铂的回收率为95%～104%。与其他测定方法进行比较,此测定方法效果较好。After the decomposition of the sample ore,α-furildioxime is used to extract and separate palladium I_2-CCl_4 extraction spectrophotometry is used to determine gold.Then trinonylamine-xylene and sodium hydroxide ultilized to extract and deextract to separate platinum,and I_2-CCl_4 extraction spectrophotometry is applied to determine platinum.Through the experiment of rate reclamation, and in comparison with other methods, a rather satisfactory result has been obtained.
