A Method for Determination of Acetamiprid Residue in Tea, Fresh Tea and Tea Infusion with HPLC-UV
摘要
Abstract
An effective method was developed for analysis of acetamiprid residue in tea, fresh tea and tea infusion by high performance liquid chromatography(HPLC)with UV detector. Tea samples were extracted by acetonitrile and Nacl Alkaline saturated solution, then purified with the Envi - Carb/NH2 cartridge, finally eluted with 10ml acetonitrile. Imidcloprid recoveries in tea, fresh tea were in the range of 68.5% -103.6% with 0.1 -1.0mg/kg acetamiprid and relative standard deviations (RSD). when acetamiprid content was 0. 033 -0. 333mg/L in infusion, The recovery was 73% - 103.8% with RSD less than 7.6%. Practical determination limit in tea, fresh tea and infusion respectively was 0.07mg/kg, 0.09mg/kg and 0. 002mg/L. the method is quick and effective. It can be used for routine monitoring of the acetamiprid residues and safety assessment research in the tea.关键词
