Commercial macroporous poly(4-vinylpyridine-co-divinylbenzene) [P4VPD], known as Reillex-425, was characterized by mercury porosimetry, nitrogen physisorption, Fourier transformed infrared (FTIR) spectroscopy and elemental analysis. Sorption rates of P4VPD for Cu(II), Co(II) and Cr(VI) ions were determined in static non-competitive experiments, at room temperature (298 K). Rapid sorption was observed, especially for Co(II), with half time, t1/2, of 1.5 min and high experimental maximal capacity…

Functionalization in copolymers based on 4VP:DVB for the removal of Cr(VI) ions from aqueous solution

Adsorption capacity for Cr(VI) ions has been evaluated on two ion-exchange resins. A gel-type precursor resin was obtained by suspension polymerization of 4-vinylpyridine and divinylbenzene monomers

Kinetic and thermodynamic studies of U(VI) adsorption using Dowex-Marathon resin

The kinetics and thermodynamics of U(VI) adsorption on Dowex-Marathon anionic resin have been studied. The process was well described by the pseudo-second order kinetic model for 0.02–0.1 M U(VI)

Cobalt and nickel uptake by silica-based extractants

ABSTRACT The pKas of ethyl/butyl phosphonate silica (EBP-Si) have been determined, and the removal of cobalt and nickel from solution was investigated as a function of various parameters and compared
