海南離子交換設(shè)備〓廣西離子交換設(shè)備【10年專注,所以信賴】 May you use your hands, will bright into hamburger, will warm bread, will be happy to make ice cream, sweet dumplings will be made, will make dumplings together, will be better made delicacies; let friendship sitting, let five one labor day and the United States, I wish you a happy happy happy! 海南離子交換設(shè)備工業(yè)用 工業(yè)純水制備系統(tǒng);交流機(jī)制與氨基酸;例如,氨基酸的兩性電解質(zhì),它包含可離子交換的陽離子(NH 3+)和陰離子(羧基),采用陽離子交換樹脂分離谷氨酸的谷氨酸發(fā)酵液的選擇性吸附。發(fā)酵液殘?zhí)羌捌渚酆衔?,顏料,蛋白質(zhì)和其他非離子雜質(zhì)分離,洗脫濃度,在功率條件下獲取谷氨酸。離子交換過程通常被認(rèn)為是化學(xué)的摩爾質(zhì)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
