Kinetics of the adsorption of polystyrene macromolecules from dilute solutions in methyl ethyl ketone on carbon black

The kinetics of the adsorption of a mixture of three polystyrenes (the weight-average molecular weight Mw = 8300, 34000, and 195000) on nonporous carbon (carbon black pretreated in the argon flow at 3800 K) from dilute solutions in methyl ethyl ketone at 298 K is studied. The kinetic dependences of the adsorption of polystyrenes on carbon black nanoparticles from solutions in methyl ethyl ketone are described by adsorption kinetics equations previously used for describing the adsorption of aromatic hydrocarbons from aqueous solutions by active carbon. The correlation between the kinetic coefficients and the molecular weights of polystyrenes is discussed.
