M17树脂对岩石中痕量硒碲的分离富集研究及应用

Separation and Preconcentration of Trace Selenium and Tellurium in Rock by M_(17) Resin

摘要: M_(17)树脂在>6mol/L的HCl介质中能同时吸附Se和Te,Se和Te可用水和丙酮分别洗脱,也可用丙酮同时洗脱。从而建立了两个新的Se、Te分离富集体系,使原子荧光测定达到纳克量级。

Abstract: Selenium and tellurium are adsorbed together on M17 resin in >6 mol/L HClmedium and can be eluted with water and acetone respectively, or eluted at once with acetone. Two new separation and preconcentration methods are devised,and determination of nanogra
