The sample was extracted with a mixture of V (acetonitrile): V (methanol) = 1:1. After filtration, the extract was defatted with petroleum ether and then it was passed through a short C18 column for pretreatment and analysed by Nova-Pak C18 column, 150 mm x 3.9 mm i.d., with V (MeOH): V (H2O) = 55:45 as mobile phase. The recoveries were 82.4%-99.8% for cyanazine, 85.6%-102.3% for atrazine and 89.1%-108.4% for simetryne. |
