【摘要】 采用微波萃取技术萃取白菜中的毒死蜱。用正交实验L₉（3⁴）考察了萃取溶剂、料液比、萃取时间、萃取温度四个因素对毒死蜱萃取效果的影响。结果表明,微波辅助萃取白菜中毒死蜱最优萃取工艺为:乙醇体积分数100%,料液比1:10,萃取时间15 min,萃取温度60℃。更多还原

【Abstract】 Microwave assisted extraction technique was applied for the chlorpyrifos extraction in cabbage.The effects of alcohol volume fraction,ratio of material to liquid,extraction time and extraction temperature on the extraction rate of chlorpyrifos were investigated,and the conditions were optimized by orthogonal experiment.The results indicated that the optimized conditions were alcohol volume fraction of 100%,ratio of material to liquid of 1:10,extraction time of 12 min,and extraction temperature of 80℃,respectively.The method is simple,fast,and environmental protection.更多还原
