MATHEMATICAL SIMULATION OF POLYMER ADSORPTION ON METAL PLATE

A mathematical model describing polymer adsorption from a solution on the surface of a metal plate is described. This model allows us to det ermine the adsorption equilibrium constant, the rate constants of adso rption and desorption, as well as the maximal amount of a polymer that may be adsorbed on the unit area of a surface plate. The dependences of these parameters on the polymer molecular mass and solvent quality were studied. The consistency of the proposed mathematical model with the experimental data on the adsorption of polystyrene from its soluti ons in good and theta-solvents on the chromium plate was demonstrated.
