摘　　要：采用离子交换法提取D-葡萄糖发酵液中的D-核糖,其中Ca2+型阳离子交换树脂具有良好的选择性,最佳吸附条件为25℃,以0.5BV/h的流速进行吸附,最佳解吸条件为80℃下,以0.5BV/h的流速进行解吸。解吸液浓缩后加入四倍量乙醇,可得到结晶D-核糖。Separation and purification of D-ribose was carried out using cation exchange resins from glucose yeast, of which Ca2+ exchange resin had the best effect. The optimal condition for adsorption is a flow velocity of 0.5BV/h at adsorption temperature of 25℃. The optimal condition for desorption is a flow velocity of 0.5BV/h at desorption temperature of 80℃. Finally, crystallized D-ribose was precipitated by adding four-fold amount of ethanol into the enriched effluent.
