Preparation of Hydrous Cerium Oxide-impregnated Fibers for the Recovery of Antimony from Aqueous Media

Hydrous cerium oxide was impregnated onto a sufonic-acid-group-containing fiber (SS fiber) prepared by radiation-induced graft polymerization and subsequent chemical modifications. Cerium ions (Ce3+) were adsorbed onto SS fiber before the formation of hydrous cerium oxide (H-CeO) via precipitation b...

Summary:Hydrous cerium oxide was impregnated onto a sufonic-acid-group-containing fiber (SS fiber) prepared by radiation-induced graft polymerization and subsequent chemical modifications. Cerium ions (Ce3+) were adsorbed onto SS fiber before the formation of hydrous cerium oxide (H-CeO) via precipitation by a reaction with a sodium hydroxide (NaOH) solution at various NaOH concentrations in the range from 0.001 to 0.1 mol L−1. The maximum percentage impregnation of H-CeO was 12 %. In the batch mode, neither SS fiber nor anion-exchange fiber removed any antimony ions, whereas H-CeO fiber captured antimony ions at a high rate.
