Adsorption on colloids

Johnson, S.B. et al.. Adsorption of organic matter at mineraPwater interfaces. 6. Effect of inner-sphere versus outer-sphere adsorption on colloidal stability, Langmuir, 21, 6356, 2005. [Pg.956]

It is, however, not very clear and definite whether the solid surfaee of a drug undergoes adsorption on colloidally suspended plasma proteins while establishing the hydrophobic characteristics Ji. [Pg.33]

Macromolecular Complex Formation and Polymer Adsorption on Colloidal Particles in Aqueous Solution... [Pg.263]

Both the macromolecular complexes and the adsorption on colloidal particles may be examined through study of the configurational properties of the terminally labeled Py-PEG-Py probe chain. One feature of interest is the degree to which the mobility of the labeled chain is reduced when it... [Pg.265]

To explore this analogy, we will review previous work on the influence of stoichiometry as well as present new results on the effect of neutralization on macromolecular complex formation. In addition, we will review very recent results for adsorption on colloidal silica and present preliminary results for the adsorption on colloidal polystyrene. The excimer to monomer emission intensity ratio, the excitation spectra, and the lifetimes of the excimer and monomer are the observable experimental parameters. [Pg.266]

Charge determines rejection in some membranes and the solubility of compounds. Charge also influences the interaction with other solutes and adsorption on colloids and membranes... [Pg.36]

Both head- and tail-type cationic vinyl monomers with long methylene chains in THF or chloroform had the maximum adsorption on colloidal silica on the respective adsorption isotherm. Above the monomer concentration giving maximum adsorption, the monomer formed micelles or clusters in bulk solution with removal of adsorbed water molecules from the silica surface. At the monomer concentration giving maximum adsorption, the adsorbed monomer was spontaneously polymerised on the silica surface in THF or chloroform without an initiator at 40C or 60C. The polymerisation mechanism was discussed. Adsorption of an anion-type monomer with a carboxyl group on delta-alumina which showed a positive zeta potential in neutral aqueous solution was higher than that on colloidal silica, but spontaneous polymerisation did not occur on alumina. 19 refs. lAPAN... [Pg.93]

In a liquid state high-resolution NMR study of adsorption on colloidal palladium, [33] it was found that under 3 atm. of 99% CO, the resonance which would correspond to carbon monoxide adsorbed on the 7.0 nm crystalline palladium colloid stabilized in methanol solution with PVP could not be directly... [Pg.518]

As we have seen, in most cases polymer adsorbs preferentially on fibers. This is obviously not true when the polymer does not adsorb on the fiber, in which case only adsorption on colloids occurs. This is the case for PEO, which does not adsorb on... [Pg.9]
