Experimental Study on Removing Calcium and Magnesium Ions in Ammonium Sulfate Wastewater with Solvent Extraction Method
In order to remove the calcium and magnesium ions in ammonium sulfate wastewater,ensure subsequent trouble-free operations of water treatment process,improve quality of ammonium sulfate solid and recover magnesium re-source,the calcium and magnesium ions in ammonium sulfate wastewater are removed with solvent extraction method in ex-periment. The P204 and kerosene are used as extractant as well as pH value of ammonium sulfate wastewater and saponifica-tion degree of P204 are adjusted so that the step-by-step removal of calcium and magnesium ions in ammonium sulfate wastewater is realized. The data support for industrial applications of this method is provided by such experimental condi-tions as determining pH values of the solution and comparing.
