A microscopic model of electrification phenomena in steady state and transient regimes has been developed. The model has been applied for analysis of experimental data failing to be explained in the frame of classical macroscopic approach. Various boundary conditions have been studied regarding the possibility of experiential data fitting. The hybrid boundary condition has been suggested for explaining steady state and transient experiments. The proposed boundary condition can be related to the coexistence of two reactions on the active surface. The first reaction runs under the diffusion control (fast reaction) and the second one is limited by the kinetics (slow reaction).
► Electrification data which cannot be explained by classical approach are analysed. ► Models with various boundary conditions are tried to fit all electrification data. ► Proposed hybrid boundary condition agrees with observed electrification data. ►The simultaneous existence of fast and slow reactions is indicated.
