| Abstract: | A method for the determination of atrazine residue in soil and maize had been developed.Samples were extracted by ultrasonic and cleaned up on a Florisil solid phase extraction column.Atrazine quantification was achieved by gas chromatography with an nitrogen phosphorus detector(GC-NPD).Compared with the available standard method of GB/T 5009.132-2003,the pretreatment of the new method was easy,rapid,cheap and less solvent consumption.The recoveries of atrazine ranged from 76.3 % to 101.3 % at the spiking l... |
