Abstract: A solid-phase chelator material usable for the purification of proteins. The solid-phase chelator material comprises a solid phase, polyamine groups bound to the solid phase and chelating groups bound to the polyamine groups. At least a part of the polyamine groups is connected with at least two chelating groups per polyamine group. Each chelating group comprises one or several aminopolycarboxylic acid groups (APA groups), with the proviso that the number of APA groups per polyamine group connected with at least two cheating groups is at least three.

Abstract: The present invention relates to separation and recovery of metals from ground alkaline batteries using anode mud (zinc electrolysis waste) and other manganese and zinc containing materials. The material commonly referred to as alkaline black (AKB) is solubilized into sulfate media and the manganese to zinc ratio is adjusted. The solution containing metals is processed using crystallization and ion exchange methods to produce manganese sulfate and zinc sulfate solutions for several possible applications.

Abstract: A filter includes a porous molding, the porous molding being a sintered product of mixed powder containing dry gel powder including an ion exchange resin and thermoplastic resin powder, or a swelled body of the sintered product. When water having an electric resistivity value of 18 MΩ·cm or more is allowed to pass through a space velocity of 1200 hr−1, the electric resistivity value of water after passage is 15 MΩ·cm or more. To provide a filter that can efficiently remove metal ions in a solution to be treated, and easily acquire a solution having an extremely low content of metal ions.
