摘要

The extraction of xylose and glucose from aqueous solution with naphthalene-2-boronic acid (N2B) in diluents of n-hexane:l-octanol (85:15 v/v) was investigated.The influence of pH,N2B concentration and phase ratio (O/W) (organic phase volume to aqueous phase volume) were investigated for an optimized condition of xylose and glucose extraction from the aqueous solution.The optimization process was analyzed using Central Composite Face-Centered Experimental Design by Design Expert Version 6.0.6 (Stat-Ease,USA).The optimum pH for extraction,N2B concentration and phase ratio (O/W) are at 11,0.083 mol/L and 1.5,respectively.The extraction percentage of xylose and glucose under these conditions are found to be 92.7 and 98%,respectively.Additionally,the sugar-loaded extractants were regenerated by dilute hydrochloric acid in the stripping process.With sufficient amount of acid available in the strip solution,the sugars are completely recovered in the aqueous phase.
