摘要：
The separation of K3VO4 and K2CrO4 plays an important role in the vanadium cleaner production process using concentrated alkaline solution as reaction media. Equilibrium solubility data for the KOH-K3VO4-K2CrO4-H2O system at (40 and 80) degrees C therefore were measured and compared with ternary KOH-K3VO4-H2O and KOH-K2CrO4-H2O subsystems, respectively. Based on the data, a strategy for effective separation of K3VO4 and K2CrO4 from the KOH-K3VO4-K2CrO4-H2O system has been proposed.
