The Influence of Organic Matter and Clay Minerals on the SPE of Pesticides from Water

The increasing number of environmentally significant pesticides requires the development of an analytical method that allows simultaneous determination of different pesticides with minimum extraction and clean-up steps. Because of the low analyte concentration levels and complex matrix composition it is necessary to preconcentrate select group of pesticides and clean-up the samples from interfering components. Procedure for pesticide analysis in water usually contain the following steps: sampling, sample preparation, fractionation and final determination. [1] In this work an analytical method has been developed for determination of pesticides alachlor, atrazine and  -cypermethrin in water. The method includes solid-phase extraction (SPE) as a method for concentration of mentioned pesticides from water samples, and thin-layer chromatography (TLC) as a separation and determination method.
