An initial-boundary value problem is considered which describes the solute transport through porous media when a chemical species undergoes adsorption or exchange processes on the surface of the porous skeleton. An \(L^1\)-contraction principle for weak solutions is proved implying the uniqueness of these solutions. The technique of entropy pairs is applied jointly with a modification of the Kružkov method of variable doubling.
