Description A new thin-layer chromatographic me/hod for the detection of carbaryl
(I-ruiphthyl N-methyl carbamate), carbofuran (2,3.dihydro-2, 2-dimethyl.7-benzofiJr.
anyl methyl carbamate) and baygon r-isopropoxyphenyl N-merhyl carbamate) from
vegetables was developed using 4:4-diaminodiphenyl su/phone as a chromogenic reagent
and benzene-acetone as developing solvent. The Rfvalues in this system were 0.25,
0.23, and 0.20 for carbaryl. carbofuran and blygon, respectively. The method is
sensitive upto 0.05 I'g ofcarbaryl. carbofuran and baygon and enables to detect as low
as 0.02 ppm of these imecticide residues from vegetables.
