Method of collection Cr(VI) from anion exchange resin column and collecting apparatus

The method of collecting Cr(VI) from an anion exchange resin column, characterized by comprising the steps of: passing a Cr(VI) high-concentration liquid through the ion exchange column filled with an anion exchange resin which has adsorbed ions consisting of Cr(VI) ions and other ions including SO4...

Beschreibung
Zusammenfassung:	The method of collecting Cr(VI) from an anion exchange resin column, characterized by comprising the steps of: passing a Cr(VI) high-concentration liquid through the ion exchange column filled with an anion exchange resin which has adsorbed ions consisting of Cr(VI) ions and other ions including SO42- and Cl- ions to saturation, so as to force out said other ions, and performing, then, a counter-flow multi-step renewal method so as to collect only Cr(VI) at a high concentration.
