摘要: 研究了强酸性离子交换纤维对偏二甲肼的吸附、解吸性能。静态吸附结果表明,反应温度对纤维的吸附效果有影响。动态吸附、解吸结果表明,纤维在离子交换柱中的装填密度、原液的浓度、流速对吸附效果有影响,用少量的氯化钠溶液可将吸附的偏二甲肼迅速解吸下来,并且使解吸液浓缩倍数达28.3倍。

Abstract: The adsorptiondesorption performance of strong acidic ion-exchange fiber (IEF) for unsymmetrical dimethyl hydrazine (UDMH) was investigated. Static adsorption showed that the adsorption effect was related to reaction temperature. Dynamic adsorption and desorption showed that the adsorption effect was also related to the loading density of IEF in the ion-exchange columnthe concentration and flow velocity of UDMH solution. UDMH can be desorbed rapidly with sodium chloride solutionand the concentration multiple reached 28.3.
