Sažetak
Some problems related to the theoretical concepts applied in studying interfacial equilibria at solid/liquid interfaces are discussed. It was shown that assumptions related to the mechanism of surface reactions and the structure of interfacial layer need to be reconsidered. The commonly used 3-layer models were considered as simplification of the general 4-layer model. The concept of the capacitors of constant capacitances was discussed. The equilibrium at the electrical interfacial layer was used to discuss the colloid stability phenomenon. The Schulze-Hardy rule, i.e. the effect of the lyotropic series was explained on the basis of equilibrium constants of counterion association with charged surface groups. It was concluded that new experimental methods are necessary for further progress in this area. The second route is to apply all existing experimental methods to one sample and to interpret the data simultaneously.
