摘要
本文以动态法为基础研究了H_(2)SO_(4)-NaBr体系P_(350)萃取色谱分离Ga-In和Tl的色谱行为,并探索了影响分离的各种因素。首次提出P_(350)萃取色谱连续分离Ga、In和Tl的新途径。拟定了岩石、矿物中痕量Ga、In和Tl全差示吸光度法检测条件。
The extraction chromatography of Ga,In and Tl was studied by the use of P_(350)as the stationary phase,polyethylenebenzyl absorption resin(X-5 type)as the carrier,and a 3 mol/L H_(2)SO_(4)-3 mol/L NaBr medium as the mobile phase.It was found that P_(350)is highly selective for the extraction of micro amounts of Ga,In and Tl,and the latter can be separated quantitatively from Fe,Al,Ti,Cu.Pb,Zn,Co,Ni,U,Th,etc.The determination was effected by photometry on a fully differential spectrophotometer,using Br-PADAP,butylrhoda-mine B and crystal violet as coloring reagents.
