Optimization for Preparation of Potassium Sulfate by Sodium Sulfate and Potassium Chloride

WT5BZ]Accordinh to the study and analysis on phase diagram of the Na +,K +∥Cl -,SO 4 2- H 2O system, new cycle for preparation of potassium sulfate by sodium sulfate and potassium chloride and treatment of surplus sodium sulfate·3potassium sulfate (Na 2SO 4·3K 2SO 4) are presented, achieve good results.
