摘要
本文报道一种离子吸附性甜菜纤维的制备方法及其离子交换性能。将甜菜糖厂副产物甜菜渣,常温下用2%～4%的氢氧化钠处理48h,可获得高吸附性甜菜纤维,其中金属离子交换容量可达0.65～1.05mmol/g。用以处理含重金属离子水表明,吸附率可达60%～85%。
This paper introduces how to prepare the sugerbeet fiber for adsorbing ions and its property of ion exchange.Treating sugarbeet dregs with NaOH solution(2%～4%)under normal temperature for48hrs can obtain high adsorptive sugarbeet fiber,the ion-exchange capacity can reach l.05mmol/g,treating water containing metal ions shows that its adsorption rate can reach60%～85%.
