成功合成了一种新型全氟磺酸型聚磷腈离子交换膜。将该膜作阳离子交换膜对污水进行电渗析处理,废水的氨氮浓度从3955mg/L降低到105mg/L,下降了约97.3%,具有较好的去除效率。
A new type of perfluorosulfonic acid polyphosphazene ion exchange membrane was successfully synthesized. The membrane as a cation exchange membrane for the electrodialysis of sewage treatment, the concentration of ammonia nitrogen in the wastewater reduced from 3955mg / L to 105mg / L, down about 97.3%, with better removal efficiency.
