| Abstract: | This paper deals with using emulsion liquid membrane technique to remove magnesium which is a new technique for wet-process phosphoric acid purification. Experiments were carried out on the basis of orthogonal experiment design. Results show that, within the range of test study, the extractant exerts a very great influence on removing magnesium in wet-process phosphoric acid, whereas the surfactant, membrane solvent and anti-extractant have a certain impact on it. |
