Abstract

Abstract Theoretical results are presented for the electrostatic double-layer interaction between a colloid particle and a long cylindrical pore, where the colloid is allowed to assume any radial position within the pore. The colloid particle is represented as a solid sphere with a given surface charge density or surface potential, or as a porous sphere with a given volumetric charge density, and the linear form of the Poisson-Boltzmann equation is employed. Analytical expressions for the potential energy of interaction are obtained and used to calculate equilibrium partitioning coefficients.
