研究了用Cl_TBP萃淋树脂在HCl介质中吸附分离镓的性能 .实验结果表明 ,在 6mol·L- 1 HCl溶液中 ,树脂对镓有良好的吸附性能 ,吸附容量可达 6 1mgGa g_resin ;被吸附的镓可用 0 5mol·L- 1 NH4Cl溶液定量洗脱 .证实该种树脂在微量镓回收固液分离中具有应用前景 .
The performance of the separation and purification of gallium in HCl medium by Cl_TBP extraction resin was studied. The experimental results show that the resin has good adsorption capacity for gallium in 6mol·L-1 HCl solution and the adsorption capacity is up to 61mgGa g_resin. Gallium can be quantitatively eluted with 0 5mol·L-1 NH4Cl solution, which shows that this resin has potential applications in the micro-gallium recovery solid-liquid separation.
