Fast, Cheap and Easy routine quantification method for atrazine and its transformation products in water matrixes using DLLME-GC/MS method

Abstract

In recent years, Brazil has been one of the largest consumers of pesticides in the world, with atrazine (ATZ) being an active principle often used in Brazilian agriculture. In this context, this study aimed at developing a fast, simple and economical routine methodology for the identification and quantification of ATZ and its transformation products, deisonopropylatrazine (DIA) and deethylatrazine (DEA), by using dispersive liquid-liquid microextraction (DLLME) as extraction technique associated with gas chromatography-mass spectrometry (GC/MS) analysis in surface water (River class 2). The best extraction condition was set using the Doehlert experimental design. Validation of the developed DLLME-GC/MS methodology showed limits of detection and quantification of 0.050 and 0.150 μg L-1 for ATZ, 0.250 and 0.500 μg L-1 for DEA and 0.250 and 0.900 μg L-1 for DIA, respectively. Parameters as matrix effect, repeatability and accuracy were evaluated. The proposed method proved to be simple, easy and low cost for the analysis of a large number of different types of aqueous samples.
