镍基碳纳米管膜电极的制备和废水氨回收效能研究
Preparation of Nickel Based Carbon Nanotube Membrane Electrode and Research on Ammonia Recovery Efficiency from Wastewater
摘要
Abstract
Aiming at the key problems of low recovery efficiency and high energy consumption of chemical ammonia re-covery technology from ammonia nitrogen waste water,a high-efficiency membrane electrode for ammonia re-covery by electrochemical method was prepared.The membrane electrode was a two-dimensional layered structure composed of polytetrafluoroethylene(PTFE)membrane,carbon nanotube(CNT)layer and hydro-philic nickel layer deposited on the CNT layer.SEM,XRD,XPS and LSV curves showed that the nickel layer significantly enhanced the ammonia recovery performance.The experimental results showed that when the ini-tial ammonia nitrogen mass concentration was 500 mg/L,the membrane electrode achieved 81.78%ammonia nitrogen removal rate and 72.43%ammonia recovery rate within 300 min,and the average ammonia flux was 1.45 g NH3-N/(m2·h-1).关键词
