Abstract

1341080 Ion-exchange ROHM & HAAS CO 7 Oct 1971 [30 Oct 1970] 46642/71 Heading B1J A process of removing ionisable material from a solution comprises passing the solution through a bed containing a mixture of an anion exchange resin and a strong acid cation exchange resin, the anion exchange resin being a weakly basic anion exchange resin having a kinetic half-life reaction time of seven minutes or less. (A method of determining half-life reaction time is described). The cation exchange resin may be a sulphated or sulphonated type or a cross-linked polymer of polymerisable acids; the anion exchanger may be the reaction products of amines with copolymers of mono- and dilvinyl aromatic hydrocarbons, or condensates of epichlorhydrin with a polyalkylene polyamine or tertiary-amine-oxide-containing resins.
