Abstract: The invention provides an efficient method to purify an aqueous solution, typically mine drainage water, especially of anions and cations present in the aqueous solution as dissolved solids, the anions and cations are removed by treatment with a positively charged extractant having at least eight carbon atoms, whereby an unstable emulsion is formed; the unstable emulsion is allowed to break into an extract phase loaded with the anions and cations, and a water phase depleted in anions and cations; a floe inherently forms in the loaded extractant phase and then the loaded extractant phase and floe are separated from the purified water and treated to remove the anions and cations as concentrated useful products; the treated aqueous phase now reduced in anion and/or cation content is also separated from the emulsion as a purified aqueous solution. The extractant phase is preferably recycled. A continuous water purification process is provided.
Abstract translation: 本发明提供了一种净化水溶液的有效方法，通常将溶解固体中的水溶液中特别是阴离子和阳离子的排泄水，特别是阴离子和阳离子矿化，通过用具有至少8个碳原子的带正电的萃取剂处理除去阴离子和阳离子 由此形成不稳定的乳液; 允许不稳定的乳液分解成负载阴离子和阳离子的萃取相，以及阴离子和阳离子中耗尽的水相; 在负载的萃取相中固有地形成絮凝物，然后将负载的萃取相和絮凝物与纯化水分离并处理以除去作为浓缩有用产物的阴离子和阳离子; 现在将阴离子和/或阳离子含量还原的处理过的水相也作为纯化水溶液与乳液分离。 萃取相优选是循环的。 提供连续的水净化过程。
