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...
