Method for reducing metal ion concentration in brine solution |
摘要 |
This invention relates to a method for removing impurities from a brine solution, the brine solution comprising a water soluble chelating agent, the method comprising the steps of:a) adjusting the pH of the brine solution to a pH of from about 2 to about 4;b) passing the brine solution through a first functionalized resin; the first functionalized resin having functional groups capable of removing multivalent metal cations from the brine solution;c) adjusting the pH of the brine solution to a pH of from about 9 to about 11.5; andd) passing the brine solution through a second functionalized resin; the second functionalized resin having functional groups capable of removing alkaline earth metal cations from the brine solution.
