Relation Between the Brunauer–Emmett–Teller and Harkins–Jura Isotherms

Nature volume 162, pages 109110 (17 July 1948) | Download Citation



H. K. LIVINGSTON1 has recently attempted to relate the Brunauer – Emmett – Teller and Harkins – Jura equations by means of the Gibbs adsorption isotherm for solid surfaces. However, he has only applied his method to one of the limiting conditions of the Brunauer – Emmett – Teller equation. We have extended this method to include the complete form of the equation, in order to direct attention to the great importance of the value of constant n in these relations.
