Abstract: | A sensitive method for the isolation, clean-up and thin-layer chromatographic semi-quantitative determination of residues of N,N'-bis(1,3,4-thiadiazol-2-yl)methanediamine ( II ) in rice is reported. The residue from II in rice was found to be its degradation product 1,3,4-thiadiazol-2-ylamine ( I ). The mean recovery by this method was 85%, and the lowest limit of determination was 0.01 mg kg?f. Using this proposed technique, the residues of I and II in various field-treated rice samples were studied. |
