聚酰胺树脂富集分离-光度法连续测定铂和钯

Spectrophotometric Determination of Platinum and Palladium by Preconcentration and Separation with Polyamide Resin

  • 摘要: 试验了在柱层析操作条件下,聚酰胺树脂对铂和钯的吸附性能。结果表明,在0.001~3.5mol/L的HCl(或王水)介质中,聚酰胺树脂对铂和钯的吸附容量分别为20.92和19.20mg/g,被酸性硫脲溶液洗脱后,用双十二烷基二硫代乙二酰二胺光度法测定。方法用于矿石中微量铂、钯的富集分离和测定,结果与等离子体发射光谱法及推荐值相符。铂、钯回收率均在93.7%~99.2%,相对误差分别为5.56%和4.44%。
