Abstract
A method for reducing the metal content in a water source includes dissolving an amount of a solubilizing anion in a low grade water comprising one or more cations under conditions suitable to formed a suspension comprising insoluble solubilizing anion-cation complexes wherein the anion comprises; and separating the insoluble solubilizing anion-cation complexes from the suspension to obtain a higher grade water having a metal content reduced by from about 50% to about 100%.

A method for reducing the metal content in a water source comprising:
- dissolving an amount of a solubilizing anion in a low grade water comprising one or more cations under conditions suitable to formed a suspension comprising insoluble solubilizing anion-cation complexes wherein the anion comprises;
- and
- separating the insoluble solubilizing anion-cation complexes from the suspension to obtain a higher grade water having a metal content reduced by from about 50% to about 100%.
A method, comprising:
- contacting a first water with a solubilizing anion to form a second water comprising a suspension of an insoluble complex of the soluble anion and a cation, wherein the first water has a resistivity of less than about 18 MΩ-cm and a conductivity of less than about 0.056 μS/cm and the second water has a resistivity that is at least 50% greater than the first water and a conductivity that is at least 50% greater than the first water.
