Description
Summary:This paper deals with the effects of pH, electrolyte concentration on electrophoretic mobility respect to zeta potential and Debye distance of clay particles. The result show that the difference of zeta potential is -2.1 mV, in the mixture water and Triton X-114. The values of the surfactants are -48.8 mV, for SDS and 46.73 mV, for CTAB, they are present a greater molecular interaction with clay surfaces. However, the zeta potential and the Debye distance decrease of 45*10-8 m2s-1V-1 in the presence of NaCl to 120*10-8 m2s-1V-1 in the presence surfactants, the pHiep of each of these mixtures in Milli-Q-water is 6.15, and in different concentration of NaCl solutions are: 6.13 in 2 mM, 6.42 in 5 mM, 6.25 in 10 mM and 6.12 in 15 mM. The result indicated that the salt concentration of the suspension solution have a consist effect in the zeta potential and Debye distance.
