title: Determination of terbacil in soil by gas-liquid chromatography with 63Ni electron capture detection.
abstract: A method is described for the determination of terbacil residue in soil. The herbicide residue is extracted with 1.5% NaOH, partitioned into an organic phase and subsequently cleaned up by passing through a Florisil column. Extract is analyzed by gas-liquid chromatography using a 63Ni electron capture detector. The procedure has a sensitivity of about 0.01 ppm, based on a 20 g sample. The method was used for the analysis of terbacil residues in the field treated soil samples.
