      Determination of atrazine in aqueous soil extracts by high performance thin-layer chromatography
      J. ESPINOZA, M. BAEZ* (*Departamento de Química Inorgánica y Analítica, Facultad de Ciencias Químicas y Farmacéuticas, Universidad de Chile, Casilla 233, Santiago, Chile)

      J. Chil. Chem. Soc. 48, 19-23 (2003). HPTLC validation of atrazine in aqueous extracts of soils on silica gel (layer thickness 100 µm) previously activated at 120 ºC for 30 min. The elution program applied to aqueous soil matrices started with 10 short isocratic runs (0.8 min) with acetonitrile – dichloromethane 30:70. Mixer was emptied after the tenth step and refilled to continue with 4 successive isocratic runs (2.5, 5.0, 7.5 and 25 min) with dichloromethane. The plate was dried for 1 min between each step and for 3 min after the last one. The plate was preconditioned with nitrogen for 15 s before each run. Quantitative determination by absorbance at 210 nm. Linearity is between 5 and 100 ng and recoveries ranging from 98.7 to 103.5 %. The detection limit is 1.5 ng and the quantification limit is 4.9 ng. Precision analysis shows an intra-assay variation between 1.48 and 5.47 %. The method can be applied to a broad range of soils including those with high organic matter content.

As example serves an aminolysis reaction mixture.
