Adsorption Kinetics Model, Taking Into Account the Electrostatic Retardation and a Specific Adsorption Barrier 

On the basis of the Henry mechanism, given in Section 4.4, and the classification of stages of the adsorption process of the previous section, the simultaneous influence of electrostatic retardation and a specific barrier can be regarded for. To do so, the expression for c(0,t) given in Eq. (7.22) is inserted into the Henry rate equation (4.32), which leads to. 

In analogy to Eq. (7.61), an expression for c(K ,t) can be obtained from Eqs (7.68) and (7.28). This relation allows to describe the first stage of a quasi-steady state adsorption process, in which the influence of the two retardation mechanisms are negligible. The electrostatic 

According to the electroneutrality condition, the dimensionless potential v /s, can be expressed in terms of adsorption and electrolyte concentration. 

At small values of T the second term in Eq. (7.69) disappears, i.e. desorption can be neglected and the following relation is obtained.
