乙酸乙酯

The herbicides in the sample was extracted with ethyl acetate. The extract was decanted into a flask through a filter paper, then the filtered solution was concentrated to dry. The dry sample was dissolved and added to 5 mL with acetone-n-hexane (30:70, V/V). It was cleaned up by Florisil, concentrated again. The sample was dissolved and adjusted to 1mL with acetone.
