Reporting data on adsorption from solution at the SOlid/SOlution interface (Recommendations 1986)

Abstract

This document is a companion to that on Reporting Physisorption Data for Gas/Solid Systems, and is designed to supplement the discussion of adsorption at the solid/solution interface given in the Manual of Symbols and Terminology for Physico-chemical Quantities and Units, Appendix II, part 1: Definitions,Terminology and Symbols in Colloid and Surface Chemistry, Pure Appl. Chem.31, 579-638(1972), section 1.1.10. The definitions of adsorption from solution used here are essentially those adopted in the Manual. A discussion is then given of the operational determination of adsorption from solution, and includes an outline of various available experimental techniques, and recommendations concerning the precautions which need to be taken to ensure reliable results. Recommendations are made regarding the form in which results should be published. The interpretation of adsorption data in thermodynamic terms is discussed as is the role of adsorption models in elucidating the molecular processes involved in adsorption. Attention is also drawn to the problems associated with the effects of surface heterogeneity on adsorption from solution. © 1986, Walter de Gruyter. All rights reserved.
