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。
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 nanogram levels of Se and Te in rock samples is realized by making use of AFS.
