Determination of amitrole in plant tissues and sandy soils by capillary gas chromatography with alkali flame ionization detection
article
A rapid and specific method has been developed for the determination of amitrole in plant tissues and sandy soils. Amitrole is extracted with ethanol, adsorbed on resin and desorbed with ammonia. After acetylation with acetic anhydride and a clean-up over a SEP-PAK silica cartridge, the amitrole-acetyl derivative is determined by gas chromatography with alkali-flame ionization detection. The gas chromatographic separation is performed simultaneously on two capillary columns of different polarity. The limit of detection for both plant tissues and sandy soils is 0.01 mg/kg. The average recoveries are 81 and 96% respectively. © 1990 Friedr. Vieweg & Sohn Verlagsgesellschaft mbH.
