Spectrophotometric Determination of Metamitron and In Its Commercial Formulations.
2015
A simple, precis, rapid sensitive and accurate spectrophoptometric methods have been developed for the estimation of Metamitron in pure form and its formulations and spiked vegetables and water samples. This method is based on oxidative coupling of Metamitron with MBTH in the presence of Ferric chloride to form green coloured product with Maximum of 615nm. The product obeyed beers law in the conceentration range 0.5-3 ml (5-30 µgml -1 ) with molar absorptivity of 1.001x10 4 . Sandells sensitivity0.004945. The assay of results was found to be goood agreement with label claim.
