Determination of Malathion Residue in Rice by Gas Chromatography

Chen Shu

Abstract

The determination of malathion residue in rice by capillary column gas chromatography was studied. The linearity is satisfactory with a correlation coefficient of 0.998 at concentrations ranging from 0.01 μg/mL to1.00 μg/mL. The detection limit and average recovery of malathion were 0.004 mg/kg and 97.2 %,respectively. This method was fast,simple and accurate,which could be applied for determination of malathion content in rice.
