| Abstract: | Objective]The research aimed to explore determining difenoconazole residue in watermelon by SPE-GC/ECD method.Method] With watermelon as tested material,the retention time,linear regression equation,correlation coefficient,and detection limit of difenoconazole were established,then their recovery rates in watermelons were determined.Result]The results showed that difenoconazole had good linearity relation,the linear range was 0.1 - 10.0μg/ml and the recovery rates were in 82%- 90%.Conclusion]The SPE-GC/ECD method was effective to detect difenoconazole residue in watermelon with better accuracy. |
