摘要
本文采用410哌啶树脂分离岩石矿物中基体元素后富集痕量Ag。交换酸度为0.25—3.5mol/LHCl介质,树脂柱上的Ag用热的0.5—1.0%硫脲解脱,并以火焰原子吸收法测定。方法简便、快速,用于岩矿中痕量Ag的富集和测定结果满意。
The separation and preconcentration of silver from 0.25-3.5 mol/L HC1
(or dilute aqua regia) is effected by using a 410 piperidine resin column. The
silver is eluted quantitatively from the resin with 0.5 to 1.0% thiourea solu-
tion and determined by AAS. The method is simple and rapid, and has been applied to the determination of silver in rocks and minerals.
