Solid phase extraction enrichment of pesticide mixtures from aqueous solutions: A quantitative FT-IR analysis

Abstract

Solid phase extraction of ten commonly used pesticides on activated carbon has been investigated. Enrichment of these pesticides was successfully achieved at ppm levels and samples were then analysed using FT-IR. The enrichment technique was employed for each pesticide sample individually and their complex mixtures. The FT-IR technique was employed for the quantitative analysis. According to the results obtained from FT-IR some pesticides were recovered at 36.8-86.5% whereas 2,4-D and endosulfan were decomposed during the extraction procedure.
