FT-IR spectroscopic detection of pesticide after sorption onto modified pumice

Organoclays can be prepared by modification of the surface with a cationic surface active compound and used for the immobilisation or separation of non-polar contaminants from polluted waters. in this work pumice is used instead of clay material. Batch system experiments were performed for the modification of pumice surface with hexade-cyltrimethylammonium bromide. Modification of pumice and then the sorption of pesticide, Fenvalerate, from water have been traced by FT-IR spectroscopy. (C) 2000 Elsevier Science B.V. All rights reserved.
