Electrochemical Determination of Prochloraz in Orange Peel after Derivatization
摘要
Abstract
A method to determine prochloraz in orange peel by electrochemistry analysis after derivatization was developed.Prochloraz was stepwise extracted by acetone and ethyl acetate,and hydrolyzed into electrochemical active 2,4,6-trichlorophenol by pyridine hydrochloride.Differential pulse stripping voltammetry(DPSV) was utilized to determine prochloraz under the optimized conditions pH 4.0 and accumulation at 0 V potential for 300 s.The results showed that oxidative peak current of 2,4,6-trichlorophenol was positively linearly correlated with its concentration within the range of 9.0 × 10-9-8.0 × 10-5 mol/L.The detection limit was 9.7 × 10-10 mol/L,and the recovery between 98.5% and 113.0%.关键词
