The anomalous sorptive behaviour of Zsm-5 and silicalite-I: Observation of low-pressure hysteresis in nitrogen adsorption
(2002)A first stage of a systematic study of the nature of the low-pressure hysteresis loop observed in the nitrogen adsorption isotherms of some MFI zeolites is presented. It was shown that the pressure at which occurrence of ...

Competitive sorption of Cu(II), Eu(III) and U(VI) ions on TiO2 in aqueous solutions-A potentiometric study
(2008)The competitive sorption of Cu(II), Eu(III) and U(VI) ions in aqueous solutions by TiO2, has been investigated by potentiometry at I = 0.1 M NaClO4, 25 °C and under atmospheric conditions. For Cu(II) ions the investigation ...

A correction to the calculation of the Gibbs free energy of adsorption for biomolecules in ion-exchange systems
(1997)We wish to propose a correction to the methodology introduced by Gerstner et al. [J.A. Gerstner, J.A. Bell, S.M. Cramer, Biophys. Chem. 52 (1994) 97-106] for the calculation of Gibbs free energies of adsorption of biomolecules ...

Near-monodisperse sodium polymethacrylates: Characterization by linear salt gradient anion-exchange chromatography
(2000)A family of six near-monodisperse homopolymers of sodium methacrylate (Mn = 1100, 3200, 5500, 7200, 14100, and 21000) is characterized by linear salt gradient anion-exchange chromatography. Although the retention times ...

Stoichiometric mass-action ion-exchange model explicit isotherms for mono-, di-, tri- and tetrameric ions
(1995)Analytical isotherms for the unhindered stoichiometric mass-action ion exchange of monomeric, dimeric, trimeric and tetrameric ions are derived. The linear increase in oligomer charge from 1 to 4 leads to an exponential ...
