摘要: Abstract The electrical conductivity of aqueous kaolinite suspensions was studied as a function both temperature and KCl concentration interpreted in terms surface conductance electrokinetic potentials. the inner part double layer shows behaviour, which differs significantly from that diffuse part. While latter is characterized by temperature-independent activation energy, ionic transport appears to be influenced additional, temperature-dependent processes at temperatures below 15 °C. Possible mechanisms for this observation are discussed it shown an increase leads more pronounced layer, then dominated portion. Finally, we estimate counterion mobility find these quantities display different dependence than corresponding bulk mobilities.
