  imidacloprid
Determination of the Insecticide Imidacloprid in Potato (Solanum tuberosum L.) and Onion (Allium cepa) by High-Performance Liqui
      
A high-performance liquid chromatography (HPLC) method has been proposed for the determination of imidacloprid residues in fortified potato (Solanum tuberosum L.) and onion (Allium cepa) and in treated potato and onion samples.
      
Sample preparation consisted of dichloromethane extraction of imidacloprid from the plant material, followed by purification of the obtained onion extract on an LC-Florisil disposable cartridge.
      
The HPLC-diode-array-detection (DAD) method has been developed on reversed phase for separation of imidacloprid with isocratic elution with a mixture of 0.01 M phosphate buffer (pH 3.15) and acetonitrile (75 : 25, v/v).
      
Spectral data obtained with DAD allow the identification of imidacloprid residue.
