海南离子交换设备工业用
工业纯水制备系统;交流机制与氨基酸;例如,氨基酸的两性电解质,它包含可离子交换的阳离子(NH 3+)和阴离子(羧基),采用阳离子交换树脂分离谷氨酸的谷氨酸发酵液的选择性吸附。发酵液残糖及其聚合物,颜料,蛋白质和其他非离子杂质分离,洗脱浓度,在功率条件下获取谷氨酸。离子交换过程通常被认为是化学的摩尔质量relationships, and the exchange process is reversible, finally reached equilibrium, the equilibrium state and the process is independent of the direction of. Therefore, the ion exchange process can be regarded as a reversible chemical reaction. But in general and multiphase chemical reaction is different, when the exchange, resin volume often change, causing the solvent molecules transfer. With a resin is placed in the solution, the following exchange reaction: A+RB = RAB + L, no matter how solution movement, in the resin surface has a layer of thin films, ion exchange by molecular diffusion through the film, apparently, solution transport stream more intense, the film thickness is small, then the liquid body the concentration is uniform. Generally speaking, resin exchange capacity and the particle size of unrelated. Therefore in the resin surface and interior has the exchange interaction, fermentation liquid by glutamate in cation exchange column, first to the resin surface diffusion, and then through the
