Approximate Analytic Expressions for Moderate Potentials

FIGURE 9.5 Comparison between the Deijaguin-Landau theory [9] and the Verwey-Overbeek theory [10]. These two theories give the same result. [Pg.227]

Although the choice of E is different for the Deij aguin-Landau theory and the Verwey and Overbeek theories, Eqs. (9.143) and (9.144) both give the identical result (Eq. (9.86)). [Pg.227]

The calculation of the potential energies V h) and h) of the double-layer interaction between two parallel plates requires numerical solutions to transcendental equations (9.105) and (9.137), respectively. In the following we give approximate analytic expressions for V (h), which does not require numerical calculation. The obtained results, which are correct to the order of the sixth power of the unperturbed surface potential i//q, are applicable for low and moderate potentials. [Pg.227]
