✦ Synopsis
to explain their experimental results. On the other hand, Adsorption isotherms and adsorbed layer thicknesses were Pefferkorn et al. have measured an increase in adsorption determined as a function of polymer charge density for three on model alumo-silica surfaces with increasing polymer samples of partially hydrolyzed polyacrylamide on b-ferric hycharge density and concluded that the adsorption is govdrous oxide particles. The amount adsorbed was found to deerned by electrostatic effects at very low charge density of crease with increasing polymer charge density. Equal values of the polymer ( 6 ) . the hydrodynamic adsorbed layer thickness were measured by Frequency dependence of the electrooptical effect in staelectric light scattering, whereas the average layer thicknesses, bilized suspensions is also investigated as a function of calculated according to R. Varoqui theory, were found to depolymer charge density. Mobility variation of the countercrease with increasing polymer charge density. Information on counterion mobility was obtained by means of frequency-domain ions when polyelectrolytes of very low charge density adelectric light scattering. The results observed are discussed in sorb at solid -liquid interfaces is also demonstrated in the terms of counterion binding to polyelectrolytes of low charge present work.
