| Abstract: | Objective:To establish the analytical method for the determination of chlopyrifos in gases of power exposure cabinet by HPLC.Methods:Hot fogging concentrate of chlorpyrifos in power exposure cabinet was collected using individual sampler equipped by two tandem porous glass plate absorbers with methanol as absorbent.The chlorpyrifos absorbent was analyzed directly by HPLC.C18 chromatographic column was applied in this method,while the mobile phase was acetonitrile(80%)-water(20%).UV detection was performed at 300 nm.Results:The sampling efficiency was 100%.RSD was less than 1%.Conclusion:The method is convenient and reproducible for the determination of chlorpyrifos in gases of power exposure cabinet. |
| Keywords: | HPLC Hot fogging concentrate of chlorpyrifos Power exposure cabinet |
