Recoveries of thiodicarb From Larvin800 (W/V) and real black gram samples Abstract: In this study an attempt was made to determine the persistence of the pesticide larvin containing thiodicarb with carbonyl functional group having ovicidal activity in black gram sample. A simple and selective differential pulse adsorptive stripping voltammetry selected for this investigation. Carbon nanotubes paste electrode used as working electrode. Reduction pattern was determined through cyclic voltamograms and the number of electrons involved in reduction process was found by millicoulometry and the reduction product collected by performing controlled potential electrolysis. Universal buffer with pH 4.0 was used as supporting electrolyte. The solutions with uniform concentration that was 1.0x10-9M used in all determinations. Calculations were made by standard addition method
