Abstract

This article describes the development of a mathematical model of solid-phase extraction. The problem is formulated based on the concepts of rate-limiting role in this process, the diffusion mechanism of transfer target components in the anisotropic capillary-porous solids, taking into account the nonlinear dependence of rate on concentration
