| Abstract: | The optimum process conditions of synthesizing potassium sulphate from waste suphuric acid in anthraquinone production through a series of steps, such as association, replacement, dissociation and so on, have been studied. Under the optimum conditions, the mass percent of H 2SO 4 in the waste acid is reduced from 23% to 0.60%,the forming salt rate of waste sulphuric acid is 89.01%, and the purity of potassium sulphate is 95.8%. |
