NKA—9大孔树脂对苹果多酚的动态吸附工艺优化（Optimization of the Adsorption Property of Apple Polyphenols on NKA—9 Macroporous Resin）
苹果多酚 大孔树脂 动态吸附
2009/9/11
为了提高对苹果多酚的分离效率，以实现工业化生产，在单因素试验得出的工艺基础上，采用响应曲面法建立了NKA—9大孔树脂对苹果多酚(AP)动态吸附和动态解吸的二次多项数学模型，验证了模型的有效性。考察了上样速率、样液质量浓度、样液pH值对AP动态吸附量以及洗脱速率、洗脱剂体积分数和洗脱剂用量对AP动态解吸的影响。优化出NKA—9大孔树脂的动态吸附工艺参数为：上样速率1.10mL/min，样液质量浓度2...
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...
