| Abstract | ||||
| A method for determination of chlorofenapyr residues in squash by HPLC is described. Samples were extracted with methanol/water, followed by liquid- liquid partitioning and clean-up in chromatographic column, concentrated to a small volume. Analysis was then determined by HPLC equipped with UV-vis detector at 260 nm. The degradation rate of chlorfenapyr SC was studied and the results indicated that final residue in squash leaves reached 0.1 mg/kg after 14 day and was undetected for the fruits, which was considered safe for human beings and animal consumption. | ||||
