Diffusion of ions under inhomogeneous conditions in the two-phase system ``initial electrolyte solution-membrane'' is investigated. Expressions for the friction constant, self- and interdiffusion coefficients are derived by means of a nonequilibrium statistical operator for an inhomogeneous case. They are applied to the system, thus the behaviour of the position-dependent selfdiffusion coefficient for NaCl near a reverse osmosis membrane is evaluated.
