| Abstract;The starane herbicide was spectrophotometrically determined by the diazotization method in a flow injection assembly. Since starane is a substituted pyridyl compound the NH2 group at the p-position was exploited for diazotization. Starane was diazotized with nitrite and the diazotized product is coupled with .BETA.-naphthol. The absorbance of the resulting azo dye was measured at 395 nm with a molar absorptivity of 1.5 * 10'4' L mol'-1' cm'-1'. The calibration graph was linear over the range of 0.6 to 10 .MU.g/mL, with a relative standard deviation (RSD) of 1.67% and a sampling through put of 60 samples h'-1'. The % recovery for the determination of starane was found to be 96%. The method was successfully applied to the determination of the active ingredient of starane herbicide in its formulation as well as in food samples. (author abst.) |
