Ion-exchanger, process for production thereof and process for removal of multicharged anions employing the ion-exchanger

摘要

An ion-exchanger is provided which comprises zirconium hydroxide supported on active carbon. A process for producing the ion-exchanger, and a process for removing a multiply charged anion by using the ion-exchanger are also provided. The ion-exchanger of the present invention has high chemical resistance, high heat resistance, high mechanical strength, and excellent ion exchange characteristics.
