High Performance Chromatographic Determination of Asulam Residue in Agricultural Products


Asulam was extracted with 0.1% acetic acid in acetonitrile, acetone, water and diethyl ether successively. Following after clean up with florisil and neutral alumina solid phase extraction cartridge, the elute was determined by HPLC with UV detector. Recoveries were carried out by spiking the standard asulam at the levels of 0.1∼0.3 and 0.05∼0.2 ppm to citrus and sugarcane, respectively. The average recoveries were 83.5 to 90.9% for citrus and 80.6 to 86.7% for sugarcane, and both detection limits was 0.01 ppm.
