Extraction of Atrazine and Its Degradation Products in Soil and Determination by High Performance Liquid Chromatography-Mass Spectrometry
土壤中莠去津及其降解产物的提取及高效液相色谱-质谱分析

Atrazine and its degradation products such as deethylatrazine (DEA), deisopropyl-(atrazine) (DIA) and hydroxyatrazine (HA) in soil samples were extracted by Waters Oasis MCX cartridges, then determined by high performance liquid chromatography-atmospheric pressure chemical ionization-collision induced dissociation-mass spectrometry (HPLC-APCI-CID-MS). The recoveries of atrazine, DEA, DIA and HA fortified in the range of 4.5-120 (ng/g) were 40.4%-82.0%, 60.6%-86.5%, 69.2%-86.1% and 30.1%-80.3%, respectively. The parent ions and the daughter ions of atrazine, DEA and DIA produced by in source CID were used to identify these chemicals. This method has been successfully applied to the analysis of (atrazine) and its degradation products in environmental soil samples near a pesticide plant.
