Claim Text:
1. A method for extraction of target components from raw liquid streams using electrochemical cells by manipulation of solvability, concentrations, and oxidation states of constituents of liquid streams by electro-effecting controllable changes of electrolytes pH values, comprising following steps: a) provide at least one electrochemical cell arranged to support redox reactions resulting in electrochemical change of oxidation states and concentration of at least one target component, and to control at least one pH value of at least one electrolyte in the at least one electrochemical cell; b) introduce at least one raw liquid stream comprising a combination of constituent ionic species into the at least one electrochemical cell; c) operate the at least one electrochemical cell to change concentrations of at least two oxidation states of at least one targeted ionic species from the constituent ionic species, and to controllably change the pH value of the at least one electrolyte in the at least one electrochemical cell; d) operate the at least one electrochemical cell to maintain a predetermined range of pH of the at least one electrolyte and to aggregate at least a portion of at least one target component pertinent to the at least one oxidation state of the targeted ionic species; e) separate and extract at least aggregated portion of the at least one target component pertinent to the at least one oxidation state of the targeted ionic species; f) separate and extract at least a part of reacted products from the at least one electrolyte in the at least one electrochemical cell.
