Determination of acetamiprid residues in sweet cherry samples.

Abstract

In this paper we have developed an analytical method for the fast determination of acetamiprid residue in sweet cherry samples. The experiment was carried out using blank extracted spiked with a solution of acetamipid insecticide at three levels. This analyte was preparation with acetonitrile from fortified sweet cherry samples using QUEChERS sample HPLC/DAD procedure. Insecticide determination and quantification were performed by x 4.6 mm using reversed phase procedure utilized an Agilent Zorbax Cj cartridge (50 mm internal diameter. 1.8 lum particle size). Mobile phase was acetonitrile/1.5% correlation CH3COOH solution. Acetamiprid showed linear calibrations from 0.05—2.5 ug/ml with mg/kg. coefficients of 0.995%. Limit of quantification (LOQ) were established as 0.014 the peak Precision values expressed as relative standard deviation of the retention times and of ranged 80-94%. areas were 0.16 and 1.29%, respectively. Recoveries of the acetamiprid were in the analysis The proposed method is rapid, simple and could be utilized for the routine of acetamiprid residues in sweet cherry samples.
