Removal, Separation and Recovery of Fe(III) and Cr Ions from Cr(VI) Plating Wastewater Containing Fe Using Persimmon Tannin Gel and Immobilized Arthrobacter nicotianae Cells
The Cr removal capability of persimmon tannin gel from the aqueous solution of Cr(VI) was first examined. Cr / g-dry persimmon gel 307 and 76 mg were adsorbed as Cr(VI) on the gel and decreased to Cr(III) in the solution , respectively. Cr(VI) was selectively adsorbed using persimmon gel from a solution (pH2) containing 7 […]
