摘要：文中考察了5种不同型号大孔吸附树脂对桑叶粗多糖溶液的脱色作用,较为系统地研究了吸附工艺条件对树脂脱色能力的影响。结果表明:AB-8树脂具有较好的脱色效果,以4.6BV/h(1BV=8 mL)的流速对3%粗多糖溶液进行吸附脱色时,处理量5BV(树脂床体积),脱色率可达82%,多糖回收率达到83%;并对树脂的再生性能进行了评价。脱色前后桑叶粗多糖的高效凝胶过滤色谱表明AB-8树脂可能对不同分子量范围的多糖都有一定的吸附作用。
The effect of five types of macro-resin on the decoloration of mulberry leaves polysaccharides was studied. The results showed that resin AB-8 represented the best decoloratlon ability. The best conditions for decoloration were determined as follows ： concentration of polysaccharide solution 3% flow rate： 37ml/h. Under these cond ery rate was 83 that AB-8 resin h itions,the decoloration rate was 82% for 5BV treatment capacity and polysaccharide recovery rate was 83%.In the mean time,the regeneration of resin AB-8 was evaluated. The experiments indicated ad a wide decoloration ability to the most of the polysaccharides.
