含V、Ga元素NaOH溶液中V与Ga分离参数的计算

Calculation of Separation Parameters for Precipitating V from V, Ga Containing NaOH Solution

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 calculation of data of Na2O-V2O5-H2O and Na2O-Ca2O3-H2O have proved the possibility of precipitating V from V、 Ga containing NaOH solution and estimated the temperature and the concentration of alkai (ratio of Na2O mass to H2O mass in solution ) ranging <40℃ and 0.3 - 0.4 respectively.
