Two-component Aqueous Systems

Two-component Aqueous Systems.—As a direct consequence of the increasing importance of the use of active carbon for water purification, there has been a recent spate of papers on the adsorption of a wide range of aqueous solutions. [Pg.102]

Stadnik and Eltekov have considered again their thermodynamic approach to adsorption from dilute aqueous solutions of microporous active carbons. An important problem in the use of the Dubinin-Radushkevich (D.R.) equation for both gas/solid and solution/solid systems is the mode of transition from this equation to the linear (Henry s law) region of the isotherm (see this Vol. p. 65). In a previous papers they found an empirical relationship between the quantity B/ 3 in the D.R. equation  [Pg.102]

In the present paper they write n n = Q and consider the transi- [Pg.103]

It is stressed that c, K, and B are unambiguously defined by the constant, B, the affinity coefficient, /3, and the temperature, T. however, there appears to be [Pg.103]
