Adsorption and Desorption of Hexachlorobiphenyl. A. Experimental Results and Discussions. B. Analysis of Exchangeable and Nonexchangeable Components

摘要

The purpose of this report is to present the experimental and theoretical results that lead to the development model for the analysis of adsorption and desorption of hexachlorobiphenyl from suspended and sedimented particles. The reversibility of the adsorption reaction between dissolved organic chemicals and naturally occurring soils, sediments, and suspended particles is of fundamental importance in the understanding of the fate of these chemicals in the environment. The issue of reversibility becomes critical if the adsorption-desorption behavior of a chemical is to be expressed quantitatively within the framework of mass balance equations.
