摘　　要：采用弱碱性阴离子交换树脂HJ-30对发酵液中1，6-二磷酸果糖的分离进行了研究。详细地研究了树脂的吸附和脱附性能。实验结果表明，HJ-30树脂对FDP的吸附量达0．28gFDP／g湿树脂，以0．05mol／LNaCl洗脱光机磷和1mol／LNaCl洗脱1，6-二磷酸果糖，产品的收率和纯度分别为92％和99．4％。Separation of fructose-1. 6-diphosphate (FDP) with HJ-30 weak-base anion exchange resin was studied. The results showed that HJ-30 resin has good performance of adsorption and desorption to FDP. Ion exchange capacity of HJ-30 resin to FDP was 0. 28g FDP/g wet resin. Inorganic phosphate was desorpted with 0. 05mol/L NaCl and FDP was desorpted with Imol/L NaCl. The yield andpurification of product were 92% and 99. 5%, respectively.
