Effect of seawater temperature on uranium recovery from seawater using amidoxime adsorbents

Synthesis of polyacrylonitrile-grafted cross-linked N-chlorosulfonamidated polystyrene via surface-initiated ARGET ATRP, and use of the resin in mercury removal after modification

“…de Santa Mariaa et al has reported some ways to chemically modify a resin-containing pendant cyano group [12]. A number of studies have shown that polymers containing AO groups can be successfully used for the treatment of metals from aqueous solutions due to the polymers' highly complex-forming capabilities with metal ions [13][14][15][16].…”

Synthesis of porous acrylonitrile/methyl acrylate copolymer beads by suspended emulsion polymerization and their adsorption properties after amidoximation

“…Consequently, the polymers with AO groups can be successfully used for the treatment of metals from aqueous solutions [11][12][13]. One of the most extensive applications of these adsorbents is the recovery of uranyl ions from seawater [14][15][16][17]. In addition, these adsorbents used for the removing of other metal ions have also been studied in literature [18][19][20].…”

Radiation‐induced graft polymerization of glycidyl methacrylate onto PE/PP nonwoven fabric and its modification toward enhanced amidoximation

“…Conventionally, amidoxime group-containing adsorbents are synthesized through the reaction of acrylic resins and hydroxylamine. The acrylic resin used is generally made from a copolymer of acrylonitrile and crosslinked monomer such as divinyl benzene, which has been extensively studied by Okamato et al 6 and Omichi et al 7 Amidoxime chelate fibers have been presented by Sugo et al [8][9][10] and Lin et al 11 and found it to be very useful for recovering uranium from seawater and enriching or separating noble metal ions from aqueous systems. Various attempts have also been made to introduce hydrophilic monomers, and enhancement of uranyl selectivity into copolymeric adsorbents by Gü ven et al [12][13][14][15] Work on fibrous systems has generated wide interest in the last decade because of improvements with respect to flow rate through such porous adsorbents and the mechanical stability of the fibers.…”
