PREPARATION AND PHYSICOCHEMICAL EVALUATION OF BIODEGRADABLE MAGNETIC Κ-CARRAGEENAN BEADS AND APPLICATION FOR CHROMIUM IONS PRE-CONCENTRATION

PREPARATION AND PHYSICOCHEMICAL EVALUATION OF BIODEGRADABLE MAGNETIC Κ-CARRAGEENAN BEADS AND APPLICATION FOR CHROMIUM IONS PRE-CONCENTRATION

This study aims to examine the ability of magnetic K-carrageenan beads as an adsorbent in solid phase extraction towards chromium ions from aqueous solution. In this study, K-carrageenan magnetic gel-beads were obtained via interphase technique. The beads were kept in 0.3 M KCl to maintain gel stren...
