For this purpose, the prepared pHEMA-(MAH)(3)-U(VI) cryogel polymer by free radical polymerization method. U(VI) was desorbed with 5.0 mol/L HNO3 and thus U(VI)-imrinted were created onto p-HEMA-(MAH)(3) cryogel polymer. To determine the optimum conditions, in the process of selective adsorption of U(VI) ion to U(VI)-imprinted p-HEMA-(MAH)(3) cryogel polymer, some parameters such as pH, flow rate, initial U(VI) concentration were investigated. Under the optimum conditions, the maximum adsorption capacity was obtained as 74.80 mg/g. Selectivity studies were also carried out in the presence of Nd(III), La(III) and Y(III) ions using U(VI)-imprinted p-HEMA-(MAH)(3) cryogel polymer. The obtained adsorption order under competitive conditions was U(VI) > La(III) > Y(III) > Nd(III).eninfo:eu-repo/semantics/closedAccessU(Vi)-Imprinted Cryogel PolymerP-Hema-(Mah)(3)Selective AdsorptionPurificationArticle386115125WOS:000541771000010Q4
