| 摘 要： | 以5种改性斜发沸石为原料,通过吸附不同碱溶液中的OH-,确定了最佳的碱溶液和改性沸石,并对OH-浓度和吸附动力学进行了研究.研究表明:钙改性沸石和镁改性沸石对Ca(OH)2溶液中OH-的单位吸附量最大;在25℃下,钙改性沸石的全吸附容量为22.21mg/g,镁改性沸石的全吸附容量为25.30mg/g;通过动边界模型理论可确定在25℃下钙改性沸石和镁改性沸石吸附OH-的动力学吸附过程主要由颗粒扩散控制.

| Abstract: | The best alkaline solution and modified zeolite were successfully determined by adsorbing OH-in the different alkaline solutions using five kinds of modified clinoptilolite as starting materials,and the OH-concentration as well as adsorption kinetic were studied.The study results showed that the OH-adsorption capacity of Mg modified zeolite and that of Ca modified zeolite were larger than others in the Ca(OH)2 solution.The maximum capacity of Ca modified zeolite was 22.21 mg/g at 25℃,and that of Mg modified... |
