| Abstract: | Determination of prochloraz residues in mushroom by solid phase extraction-high performance liquid chromatography(SPE-HPLC) has been conducted.In the method,acetonitrile and celite545 were added into representative sample,and the mixture was homogenized at ultra high speed.After filtration,the extract was purified by a liquid-liquid partitioning process with NaCl solution and dichloromethane.The dichloromethane phase was evaporated to dryness,and the residue was dissolved with acetonitrile.Then,the organic ... |
