Synthesis of amidoximated polyacrylonitrile/sodium alginate composite hydrogel beed and its use in selective and recyclable removal of U(VI)
In this study, a novel type of composite hydrogel bead (PSH) was prepared by mixing of amidoximated polyacrylonitrile (PAO) and sodium alginate (SA). The structure of PSH was characterized with FT-IR, SEM and XPS. The influences of adsorption conditions on uranium(VI) adsorption by PSH were investig...

| description | In this study, a novel type of composite hydrogel bead (PSH) was prepared by mixing of amidoximated polyacrylonitrile (PAO) and sodium alginate (SA). The structure of PSH was characterized with FT-IR, SEM and XPS. The influences of adsorption conditions on uranium(VI) adsorption by PSH were investigated by batch experiments. The kinetic and isotherm data were consistent with pseudo-second-order and Langmuir models, respectively. PSH displayed high selective adsorption capacity for uranium(VI). The maximum adsorption amount can reach 133.33 mg g

. PSH was separated from aqueous solution easy and showed an excellent regeneration capacity. This research demonstrated that PSH had a broad prospect of application in the field of repairing uranium-containing wastewater. |
