CPF-V型泡沫塑料富集HCSDAA吸光光度法测定矿石中微量钯
DETERMINATION OF RARE PALLADIUM IN ORE BY CPF-V FOAMED PLASTIC ENRICHMENT HCSDAA SPECTROPHOTOMETRY
【摘要】 利用含有二苯基硫脲螯合基团的新型 CPF- V型泡沫塑料对分解后的矿样进行富集钯的处理 ,洗脱分离后用 2 -羟基 - 3-羧基 - 5 -磺基苯基重氮氨基偶氮苯 (HCSDAA)吸光光度法测定矿石中的钯 ,反应的酸度控制在 p H9.3~ 10 .6 ,共存离子基本不干扰测定 ,钯的最低检测限为 0 .0 9(μg· m l- 1 ) ,通过方法的回收率试验 ,并与其他测定方法进行比较 ,得到了较为满意的结果 ,回收率在 95 .7~ 10 4 .0 %之间。
【Abstract】 After the washing out and separation of the CPF-V foamed plastic enrichment palladium containing dimethyl thiourea chelate,the bHCSDAA spectrophotometry is used to determine the rare palladium in our.The acidity for the reaction is within the scope of pH 9.3~10.6.The common ions do not affect the determination and the lowest detection limit of Pd is 0.09 μg·ml -1.Satisfactory result is obtained in comparison of this method with other detection method,and the recovery ranges from 95.7%~104%.
