Document Type and Number:
Japanese Patent JPH0810763
Kind Code:
A
Abstract:
PURPOSE: To obtain a treating method for economically separating, removing and recovering harmful lead ion from various solutions containing lead ion with improved energy consumption.
CONSTITUTION: Various solutions containing lead ion are brought into contact with a chelate ion exchange resin having phosphoric acid group, phosphine group and/or phosphonic group to adsorb the lead ion into the resin and to separate and remove.
