title: Determination of carbamate herbicide asulam in peaches following fluorescamine fluorigenic labelling.
abstract: Because of the primary aminic character of asulam, it is readily labelled with fluorescamine. A study of the variables affecting the derivatization reaction has been made. Two analytical approaches, that is, direct, synchronous spectrofluorimetry have been tested, and they both show good analytical performances. The linear dynamic range of the synchronous approach is 0.043-0.214 mug/ml and the relative standard deviation is 1.6%. The methods have been applied to the determination of asulam residues in peaches with recoveries of 85-106%.
