| Abstract: | The adsorption property, the operating life, the operating exchange capacity and regeneration of D412 macroporous phosphonomethylamina chelating resin for removing Ca2+, Mg2+ and Fe2+ from high pH brine of alkali production by ionic membrane were investigated. The resin showed good physical-chemical and kinetic property, high exchange capacity, excellent durability. |
