DETERMINATION OF ATRAZINE IN AQUEOUS SOIL EXTRACTS BY HIGH-PERFORMANCE THIN-LAYER CHROMATOGRAPHY

A high performance thin layer chromatography (HPTLC) method for the determination of atrazine in aqueous soil extracts was studied. To verify the applicability of the method in environmental concern studies, soil samples having different organic matter (OM) contents (1.4-24.0 %) were used. Developme...

To verify the applicability of the method in environmental concern studies, soil samples having different organic matter (OM) contents (1.4-24.0 %) were used.
