利用褐藻酸钠生产污水提取褐藻糖胶

Extracting Fucoidan from Sewage of Producing Sodium Alginate

从海带综合利用生产褐藻酸钠、碘、甘露醇后的污水中提取褐藻糖胶的实验条件研究表明 :Na2 CO3 溶液与污水用量比 (体积比 )为 1∶5 5 ,pH为 5 5 ,乙醇浓度为 6 0 % ,复水温度为 75℃时 ,提取的粗褐藻糖胶中褐藻糖的质量百分比浓度最大达到 2 2 5 % 。

The experiment on extracting fucoidan from sewage of producing sodium alginage states:When V [Na 2CO 3(1mol/L)] :V sewage is 1∶5 5,pH is 5 5,alcohol consistency is 60%,dilute temperature is 75℃,quality percent consistency of Fucose of crude polysaccharides is 22 5% Viscosity experiment shows:The fucoidan extracted by the technology is similar in property to which is extracted directly from dry kelp.
