萃取色层分离法目前已成为岩矿测试工作者研究痕量元素之间分离的重要手段,本文研究了在氢溴酸体系中P—350萃取色层连续分离镓、铟的行为。试验结果证明,以聚二乙烯苯为载体,P—350为固定相,5.5mol/L H_2SO_4为解脱剂相继解脱镓和铟,不仅分离效率高,操作简便,而且具有良好的选择性。经分离后的Ga和In用丁基罗丹明B光度法测定,准确可靠,并
Extraction chromatographic separation method has now become an important means for rock and mineral testing workers to study the separation of trace elements. In this paper, the behavior of continuous separation of gallium and indium from P-350 extraction chromatography in hydrobromic acid was studied. The experimental results show that P-350 as stationary phase, P-350 as stationary phase and 5.5mol / L H 2 SO 4 as releasing agent can release gallium and indium one after another, which not only has the advantages of high separation efficiency, simple operation, but also good selectivity. After separation of Ga and In with butyl rhodamine B photometric determination, accurate and reliable, and
