Abstract :The present paper reports results of the thermodynamic study of adsorption of 2 optical brighteners insert ignore into journalissuearticles values(Tinopal UP and Leucophor AP); on pulp. The entropy non-homogeneity of the pulp surface was confirmed and the coefficients of entropy non-homogeneity were determined. The entropy effect on the variation of Gibbs free energy of the process studied was followed.
