Abstract
A method for producing a metal ion exchanger with increased absorption and regeneration capabilities that comprises treating an ionically inert porous support with a solution of metal oxychloride. Said metal oxychloride precipitates within the pores of the support and bonds thereto regardless of the pH of the system. The ion exchanger is then used as a medium through which sea water or other brine solutions are passed and inorganic ions and trace organics selectively absorbed. The ion exchanger is easily regenerated after absorption through treatment with sodium hydroxide and hydrochloric acid and can be reused immediately.
