In view of the desorption of gallium by resin adsorption,the effects of different desorption types,liquid-solid ra-tio,desorption concentration,desorption time and desorption temperature on the desorption of Ga,Al,V were investigated.The results show that hydrochloric acid is the best desorption agent,and the desorption efficiency of Ga will be reduced if the concentration of hydrochloric acid is too high or too low.Ga can be completely desorbed when the concentration of hy-drochloric acid is controlled at 1 mol/L,and the desorption rates of Al,V are low.Temperature has little effect on the de-sorption of Ga,Al,but has great effect on V.The higher the temperature is,the better the desorption effect of V is.After comprehensive consideration,1 mol/L hydrochloric acid was mixed with LSC-600 resin at a liquid-solid ratio of 10∶1,and the complete desorption of Ga could be achieved after 20 min desorption at 25℃.At this time,the desorption rate of Al was lower than 13%,and the desorption rate of V was basically 0.
