INFLUENCE OF PARTICLE AGGREGATION IN SUSPENSIONS ON ION ADSORPTION

The influence of the interaction of double layers (DL) of dispersed pa rticles on ion adsorption was discussed. The solution of the Poisson-B oltzmann equation, provided the surface potential was constant, made i t possible to obtain the dependence of the ion adsorption on DL overla pping, which was characterized by the potential in the symmetry lane o r the force of the ion-electrostatic interaction of particles. Approxi mate expressions for calculating both overlapped and non-overlapped DL were derived for the case of small surface potentials. It was shown t hat the DL interaction that accompanies aggregation of the dispersed p articles may strongly affect the measured values of ion adsorption.
