摘　　要：通过动态脱盐实验,研究了不同离子交换树脂对1,3-丙二醇发酵液的脱盐性能。实验结果表明,采用D001和732阳离子树脂脱盐时发酵液的最佳流速分别为40,60 m L/min,D001阳离子树脂对发酵液的处理效果较好;D315阴离子树脂和D363阴离子树脂的最佳流速均为40 m L/min。树脂再生实验发现D363阴离子树脂消耗较少的氢氧化钠溶液。Through the dynamic adsorption desalination methods, the desalination properties of different iton-exchange resins to 1,3-propanediol fermentation liquid were studied. The results show that the optimum desalination flow rate of D001 cation resin or 732 cation resin is 40,60 mL/min, respectively, and ion exchange resin D001 is better;The optimum desalination flow rate of D363 anion resin and D315 ani- on resin are 40 mL/min. The reReneration exoeriments show that D363 anion resin need less amount of NaOH solution.
