| Abstract: | A method for the simultaneous determination of residue of atrazine and cyanazine in soil is reported. The sample was extracted with acetonitrile-methanol system and de fatted with petroleum ether. Then after it passed through an Al2O3 column, the sample can be separated on a Nova-Pah C18, column using a mobile phase of methanol-water(55: 45,V/V) and determined with an ultraviolet detector at 228 um. The detection limit were 0. 3 ng for a trazine and 0. 2 ng for cyanazine. Recoveries were 83. 4%-102. 3% for atrazine and 82. 4% -93. 5% for cyanazine. |
