Abstract
PURPOSE: To reutilize a used cation exchange resin which has been conventionally abandoned, as a valuable drying agent by sufficiently washing a used cation exchange resin treated by a strong acid solution and, moreover, by a strong alkali solution and, thereafter, drying the same.
CONSTITUTION: To a used cation exchange resin, a strong acid solution such as hydrogen chloride or a strong acid solution and a strong alkali solution such as NaOH is passed to remove impurities adsorbed and adhered in fine pores or to a surface of aformentioned resin particle. Subsequently, to this cation exchange resin treated by the chemical solution, a predetermined amount of water is passed to extrude said chemical solution and, succeedingly, a predetermined amount of water is passed to wash said cation exchange resin. Subsequently, the cation exchange resin completed from washing is drained and dried by air to reduce a moisture content to about 30% and, thereafter, dried at a temp. of about 110°C in the conventional dryer to lower the moisture content to 5% or less, especially, 2% or less to obtain a drying agent.
