摘要
A method for analyzing drugs of the 2. AB-DDR for residues of chlorpropham, metobromuron and chlorbromuron is proposed. It is based on the detection of aniline derivatives resulting from alkaline hydrolysis. Herbicide concentrations greater than 0.25 mg/kg drug may be detected and semiquantitatively estimated by thin-layer chromatography. Smaller amounts of herbicide residues are detected gas chromatographically (using an electron attachment detector) after bromination of the hydrolysis products. The limits of detection are: chlorpropham, 0.006 mg/kg drug; chlorbromuron, 0.008 mg/kg drug; and metobromuron, 0.04 mg/kg drug. For impregnated drugs, the recovery rates lie between 82 and 102%. The herbicide residues are released to infusions at a varying extent, depending on the kinds of drugs used.
