CL-TBP萃淋树脂吸附分离镓(Ga)研究

Study on Adsorption and Separation of Gallium with CL-TBP Extraction Resin

本文研究了 Cl- TBP萃淋树脂从酸性溶液中吸附分离镓的性能 ,结果表明 ,在 6mol· L-1HCl介质中 ,树脂对镓有良好的吸附性能。可有效地从含镓溶液中分离富集镓。被吸附的镓可用 NH4 Cl溶液定量洗脱 ,对吸附过程机理进行了初步研究 ,证实吸附为离子交换过程。

The performance of adsorption and separation gallium from acidic solution by Cl\|TBP extraction resin were studied.The results show that the resin can effectively separate and enrich gallium from solution containing gallium in 6mol·L -1 HCl medium.The gallium adsorbed can be quantitatively eluted with NH 4Cl soutions.Tentative studies confirm that the mechanism of adsorbing gallium process by the resin is ion\|exchange type.
