摘要：本文采用苯基硼酸/季銨鹽離子對溶劑萃取D-塔格糖。通過單因素實驗，考察pH、苯基硼酸濃度、溶劑比對D-塔格糖萃取率和選擇性的影響。進一步利用響應面分析優化得到最佳萃取條件為：pH 11，苯基硼酸濃度0.10 mol/m3，溶劑比1，此時D-塔格糖的萃取率為65.69%，選擇性系數為14.67，D-塔格糖的回收率為92.28%。

關鍵詞：萃取，苯基硼酸，D-塔格糖，響應面分析

Abstract: In this study, the solvent extraction of D-tagatose with an ion-pair of phenyloronate anion and quaternary ammonium cation were investigated .The influence of pH, PBA concentration and volume ratio(O/W) on extraction rate of D-tagatose and the selectivity for D-tagatose from the aqueous solution were examined by single factor tests. It was showed that the optimized conditions were pH 11, PBA concentration 0.10 and volume ratio(O/W) 1 using Central Composite Face-centered Experimental Design by Design Expert Version 7.1.6(Stat-Ease,USA), and in this condition, the extraction percentage、selectivity for D-tagatose and the recovery extraction percentage was obtained to be 65.69%、14.67 and 92.28%.

Key words: extraction, PBA, D-tagatose，RSM
