Document Type and Number:
Japanese Patent JP5284378
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rhenium recovery method and system from waste acid which can satisfactorily reduce the load of the impurity removal in a purification process.SOLUTION: There is disclosed a method for recovering rhenium from a waste acid which contains at least rhenium and bismuth. The method includes the steps of: passing a waste acid through an anion exchange resin to allow rhenium and bismuth to adsorb on the resin; passing an eluent through the resin on which rhenium and bismuth have adsorbed to elute rhenium and the bismuth from the resin; and separating and recovering rhenium and bismuth contained in the liquid after elution by pseudo-moving bed type chromatography.
