摘要 采用ZB-1强酸性阳离子交换纤维柱和ZB-2强碱性阴离子交换纤维柱联合法制备医药级蔗糖。用石墨炉原子吸收光谱法测定医药级蔗糖痕量的铅,测定其比旋光度及电导率。结果表明,当ZB-1强酸性阳离子交换纤维和ZB-2强碱性阴离子交换纤维为2.0 g和3.5 g,上柱液质量浓度为0.30 g/mL,pH为7.0,流速为5.0 BV/h时,可有效除去蔗糖中的各种杂质。该法制备的医药级蔗糖指标符合英国药典2000版标准,收率高达92.63%。 Using the strong acid cation exchange fiber column and strong basic anion exchange fiber column,the pharmaceutical grade sucrose was preparated.The graphite furnace atomic absorption spectrometry determined the trace amounts of lead,and the polarimeter determined the specific rotation,and the conductivity meter determined the conductivity.The results showed that the quality of the strong acid cation exchange fiber,the quality of the strong basic anion exchange fiber,the concentration,the pH and the flow rate were 2.0 g,3.5 g,0.30 g/mL,7.0 and 3.0 BV/h,respectively.Under this optimum technology conditions,the strong acid cation exchange fiber could remove the impurities in the edible sugar.The pharmaceutical grade sucrose met the pharmaceutical grade sucrose standard of British Pharmacopoeia 2000,and yield could reach 92.63%.
