Abstract
The loss of K2O in production of potassium dihydrogen phosphate with monocalcium phosphate and potassium sulphate was studied.By means of three-factors quadratic regression orthogonal design method,the influences of reaction,temperature,reaction time,molar ratio of potassium sulphate to monocalcium phosphate and ratio of liquid to solid on K2O recovery were investigated.The optimum conditions of getting the maximum K2O recovery were obtained.
