| 摘 要： | 采用四种大孔ＮＨ＋４型阳离子交换树脂Ｄ００１、Ｄ６１、Ｄ７２、Ｄ１１３从等电点结晶母液中回收谷氨酸，其中Ｄ６１树脂取得了良好的交换效果。Ｄ６１树脂吸附谷氨酸的离子交换等温线可以用Ｆｒｅｕｎｄｌｉｃｈ方程表示ｑ＝５．３３９（Ｃ＊）０．４４７８。将Ｄ６１树脂上柱交换，测出了不同空间流速下的穿透曲线，得到了适宜的流速为２．１６ｍｌ／ｍｌ．ｈ。

| Abstract: | In this paper, four different macroporous NH + 4- m form ion exchanger resins, D001,D61,D72,D113, were used for the recovery of glutamic acid from the mother liquor of isoelectric point crqstallization. Of these resins, D61 was the best one. An ion exchange isothermal equation was expressed with Freundlich model as q=5.339(C *) 0.4478 . It simulates the experimental data well. Furthermore, the breakthrough curves at a fixed bed with D61 resin were determined. A optimal volumetric rate, 2.16ml/ml·h was obtained. |
