FT-IR Spectroscopic Detection of Pesticide after Sorption onto Modified Pumice

Abstract

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 hexadecyltrimethylammonium bromide. Modification of pumice and then the sorption of pesticide, Fenvalerate, from water have been traced by FT-IR spectroscopy.
