REGENERANT FOR ION-EXCHANGE RESIN FOR WATER SOFTENER CAPABLE OF PREVENTING SOIL CONTAMINATION AND TOXICITY DUE TO SODIUM CHLORIDE

摘要

PURPOSE: A regenerant for ion-exchange resin for a water softener is provided to replace salt when the ion-exchange resin is regenerated by functionalizing the surface of a silica nano-particle to a cation functional group, and to improve economical efficiency of the regenerant.;CONSTITUTION: A regenerant for ion-exchange resin for a water softener is manufactured by attaching a cation functional group on the surface of a silica nano-particle. The size of the silica nano-particle is 50-500nm. The cation functional group is one or more component selected from a group consisting of a Tributyl ammonium group, a Tetradecyl dimethyl ammonium group, a diedecyl methyl ammonium group and aminoethylaminopropylpropyl.;COPYRIGHT KIPO 2010
