Title:
ELUTING METHOD FOR METAL ADSORBED BY CHELATING AGENT
Document Type and Number:
Japanese Patent JPS6142335
Kind Code:
A
Abstract:

PURPOSE: To make it possible to recover a metal component in a liquid form up to a high concn. region at a high elution speed, in eluting the metal adsorbed with a chelating agent by an eluent, by using a basic aqueous solution containing a specific amount of sulfide as the eluent.

CONSTITUTION: In eluting the metal (e.g., In, Ga, Pd, Ge, U, Au, Pt) adsorbed with a chelating agent by an eluent, an aqueous solution respectively containing 0.005W3N of water soluble inorg. sulfide (e.g., Na2S) and 0.1N or more of a basic compound (e.g., NaOH) is used as the eluent. As a result, the metal component can be recovered in a liquid form up to a high concn. region at a high elution speed and the derioration of an adsorbent is not substantially brought about.
