摘要
为探索高效快速降解甲氰菊酯农药的新方法,利用等离子体处理含有甲氰菊酯农药残留的山东寿光城阳青大白菜,研究了等离子体处理对甲氰菊酯农药残留降解效果的影响,采用响应面法对其影响因素进行了优化设计。结果表明:等离子体处理对大白菜中残留的甲氰菊酯降解有明显的效果,降解率均在70%以上,各参数影响顺序为:作用时间>作用功率>极距,较佳工艺为:作用时间30 s、作用功率200 W、极距3 cm时,降解率可达98.78%。该研究可为等离子体法降解果蔬农药残留提供参考。
To obtain a new method of pesticide residue degradation in fruits and vegetables, the effects and influencing factors of fenpropathrin residue degradation in Shandong Chengyang Cyan Chinese cabbage were studied by using plasma through response surface methodology. The results showed that plasma had an excellent effect on fenpropathrin residue-degraded in Chinese cabbage. The degradation rates were all more than 70%,and the influence strength of the parameters was application time power electrode distance. The optimum residue degradation conditions of fenpropathrin were application time 30s, power 200 W and electrode distance 3 cm, and the maximum degradation rate was 98.78%. This paper provide a reference for pesticide residue degradation in fruits and vegetables.
