苹果汁中溴氰菊酯残留的大孔树脂吸附分离（Separation of Deltamethrin Residue in Apple Juice with Macroporous Adsorption Resin）
溴氰菊酯残留 苹果汁 大孔吸附树脂
2009/8/11
为去除苹果汁中残留的溴氰菊酯,利用大孔吸附树脂对苹果汁中溴氰菊酯的吸附性能及参数进行了研究。通过树脂吸附溴氰菊酯的静态吸附试验, 对大孔吸附树脂进行了筛选,同时，在动态吸附试验的基础上，对最佳吸附动态条件进行了优化，结果表明：LS—803型树脂对溴氰菊酯的吸附能力最强, 其静态吸附时间为100min；通过正交试验确定了LS—803型树脂较佳的动态吸附条件为: 温度20℃、苹果汁质量浓度110g/L...
