对Na_2O-V_2O_5—H_2O系和Na_2O-Ga_2O_3-H_2O_5系的饱和溶解度数据进行了一系列理论计算,论证了含V、Ca元素NaOH水溶液中V与Ga分离的可能性,并估算出分离的温度、碱度(溶液中Na_2O质量/溶液中H_2O质量)范围分别为<40℃和0.3～0.4。
A series of theoretical calculations were carried out on the saturation solubility data of Na_2O-V_2O_5-H_2O and Na_2O-Ga_2O_3-H_2O_5 systems. The feasibility of separating V from Ga in aqueous NaOH solution containing V and Ca is demonstrated. The temperature, Alkalinity (mass of Na 2 O in solution / mass of H 2 O in solution) ranged from <40 ℃ and 0.3 ~ 0.4, respectively.
