Physico-chemical treatment methods for soil remediation
conference paper
For the purpose of this paper physico-chemical methods are defined as all remedial methods that remove contaminants from soil or destroy the con taminants in the soil, with the exception of thermal methods and micro biological methods. This definition excludes the methods which are aimed at the stabilization and/or solidification of contaminated materials; these are discussed in separate papers. The most important remedial methods that do meet the definition are: - Extractive methods (including flotation and classification); - Stripping (both air- and steam-stripping); - Chemical detoxification. In principle these methods can be applied either in-situ or after excava tion of the contaminated materials, each application having specific limitations and possibilities. The principles of physico-chemical methods, their potential applicabili ties, and their state of the art are described in this paper. Prior to this, attention will be paid to the interactions that may occur between soil and contaminants, since a better understanding of these interactions is required for insight into the possibilities and limitations of the various physico-chemical methods.
