Abstract: Microwave-assisted extraction, integrated with column chromatography and gas chromatography with a nitrogen-phosphorus detector, was presented for residual determination of atrazine in corn. The recoveries of the method range from 92% to 104%. The relative standard deviation is between 1.47% and 4.35%. Compared with the method in China National Standards (GB/T 5009.132-2003), this is a rapid method with less solvent consumption and better precision and accuracy.

Key words: corn, atrazine, determining method, microwave-assisted extraction
