【摘要】 初步研究了4种活性炭和7种大孔离子交换树脂对低聚木糖超滤液的脱色效果。结果表明,结果表明,糖用活性炭HC-303型活性炭和阴离子树脂D750对低聚木糖溶液具有较好的脱色效果。HC-303型活性炭在80℃,60min、pH3.0、160r/min、添加量为3.0g/L时,其脱色率达到95.4%,还原糖损失率为4.8%;大孔离子树脂D750在添加量为4.50%(w/w,对固形物),脱色3.0h,脱色率可达96.5%,脱色引起的糖分损失率为6.0%。更多还原

【Abstract】 The effect of 4 types activated carbon and 7 types of macroporous resins on decoloring on UF permeate of xylo-oligosacchardies(XOS)were investigated.Results showed that HC-303 powder activated carbon and macroporous resin D750 performed best.Under conditions of 80 ℃,60min、pH3.0、160r/min、3.0 g/L of activated carbon addition, 95.4% colorants in the UF XOS were removed and 4.8% sugars was lost.In the application conditions of 3.0 h reaction time and 4.50% dosage of macroporous resin D750 (based on the dried solids), the adsorption rate was 96.5% and 6.0% sugars was lost.更多还原
