摘要
本法是在H_2O_2-FeCl_3-NaCl存在条件下,以盐酸介质为上柱液,用HBr、H_2O及抗坏血酸分步解脱Ga,In,Tl,然后用丁基罗丹明B法测定Ga,In。用结晶紫法测定Tl。
This paper has studied the column behaviour of mixed extraotion chromatographic separation of Ga, In and T1. The medium of the sample selution is made to be 1 mol/L HCl-15% NaCl-0.05% FeCl_3-0.05% H_2O_2. Ga, In and T1 can be quantitatively concentrated on the column and then separately liberated by 1 mol/L HBr(Ga), H_2O(In) and 1% ascorbic acid(T1). The method is used for the photometric determination of Ga and In with bu tylrhodamine B and T1 with crystal violet. A satisfactory result is achieved.
