Determination of Imidacloprid in Corn by HPLC

Zhang Ying-xuan

Abstract

A method was reported for determination of Imidaclorid in corn by high performance liquid chromatography(HPLC).Imidacloprid was extracted with methanol in an ultrasonic bath,and was purified through Sep-Pak column,then was separated with UV detection.The content of Imidacloprid was determinated by external standard method.The determination was limited by 0.05mg/kg.The recovery was more than 80% and RSD was under 7%.
