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: Method and composition for decomposing and detoxifying chemical warfare agents, organic toxic compounds (e. g., pesticides), and for removal of contaminants in materials including fuels. The method and composition are based on ferrate (VI). The ferrate is typically applied to a contaminated surface or volume with a phase transfer catalyst and/or with a carrier.
