| 摘 要： | 建立了由亲水性离子液体四氟硼酸N-丁基吡啶BPy]BF4和(NH4)2SO4形成的双水相体系萃取分离芦丁的新方法。研究了(NH4)2SO4浓度、芦丁溶液浓度、离子液体用量和溶液酸度对双水相形成和萃取率的影响。结果表明,当双水相体系组成为:(NH4)2SO41.5 g,2.0 mL离子液体,1.0~1.2 mL芦丁溶液,溶液酸度在pH4~6范围内,该离子液体双水相体系对芦丁有较高的萃取率(E%>90)。

| Abstract: | A new method for the extraction and separation of rutin with aqueous two-phase system formed by a room temperature water-soluble ionic liquidBF4(nitrogen-butyl pyridine tetrafluoroborate) and phase-forming salt(NH4)2SO4 was studied,and effect of concentrations of ionic liquid,salt and rutin and pH value on extraction efficiency were investigated systematically.With the addition of 1.0~1.2 mL rutin,2.0 mLBF4,1.5 g(NH4)2SO4 and pH 4~6,ionic liquid aqueous two-phase system had the highest extraction efficiency(E%> 90). |
