On the theory of adsorption kinetics of ionic surfactants at fluid interfaces

The kinetic equation to describe the adsorption process of ionic surfactants (derived in part 1) will be solved numerically. The results show the effect of parameters such as ion valencyz, thickness of theDL x^–1, and surfactant parameters_eq,K, andK_ads on the adsorption process. The results can be used to decide whether the model can explain experimental data on charged surfactant molecules or not.Nomenclature c concentration - c_e bulk concentration in equilibrium - C =c/c_e dimensionless concentration - D diffusion coefficient - e proton charge - F Faraday's constant - f₀ =e/kTdimensionless potential - k Bolzmann's constant - K_ads rate constant of adsorption - K_des rate constant of desorption - K(f₀) coefficient of electrostatic deceleration - K =_eq/c_e Henry's constant - R gas law constant - t time - T absolute temperature - z electrovalence - ₀ adsorption of ions - _eq equilibrium value of _o - =₀/_eq dimensionless adsorption - , constants - dielectric constants - x Debye-Hückel reciprocal distance - =Dt/K² dimensionless time - electric potential
