中文摘要: 以脱色率和甜茶甙的保留率作为考察指标,对9种树脂进行了筛选,并通过静态吸附试验和动态的单因素试验对筛选出的树脂的最佳脱色条件和再生条件进行了研究。结果表明:D296阴离子交换树脂的脱色效果最好,其最佳脱色条件为:上柱液pH6.5,流速2.0 BV/h,上样浓度(以多酚浓度计)3.0 mg/mL。最佳再生条件为:用3 %的NaOH 和HCl溶液先后冲洗树脂至流出液近无色。
Abstract:Nine kinds of macroporous resin were selected by studying the decoloration rate and the retention rate of rubusoside. The static and dynamic adsorption test of single factor experiment had been done to investigate the best decolorization conditions and regeneration conditions of the selected rein. The results showed that D296 macroporous resins was the best one. The optimal decolorization conditions were as follows:the pH 6.5,the flow rate 2.0 BV/h,concentration of sample 3.0 mg/mL(the concentration of polyphenols).The optimal regeneration conditions were:flushing the used macroporous resins with 3 % NaOH and HCl solution until the effluent solution was nearly colorless.
