A method for determining spirodiclofen in orange and soils was established by using GC with ECD, acetone as extractant and methylene dichloride as extractive solution, purification by Florisil cartridge. The results of optimized experimental conditions showed that linearity was good range from 0.141 μg/L to 5.65 mg/L, the minimum detection limits 0.003 5 mg/kg, spiked recoveries at 0.050 mg/kg, 0.500 mg/kg and 1.00 mg/kglevels of blank samples from 82.2% to 110%, RSD of duplicates from 2.6% to 9.8%. |
