| 摘 要： | 对Ls-40型大孔吸附树脂和D113型离子交换树脂对二甲胺的吸附效果研究,分为小试实验和中试实验两部分。实验结果表明：Ls-40型大孔吸附树脂和D113型离子交换树脂的静态吸附量大、再生稳定性高,洗脱液流速对吸附能力影响大,再生液盐酸回流脱附比直接脱附效果好,脱附液盐酸的浓度过大将减弱脱附。

| Abstract: | Ls-40 macroporous resin and D113 ion exchange resin were used to study separation and removal of low-concentration dimethylamine from wastewater.The research was divided into small scale experiment and pilot test with the static and dynamic experimental methods.The results show that the static adsorption capacity of the two resins is large,and they have good stability after regeneration.The flow rate of eluent has great effect on adsorption capacity.The reflux desorption of renewable liquid,hydrochloric aci... |
