Zexin Qian

PhD Researcher


My research focuses on the selective membrane separation of monovalent cations, especially between Na+ and K+, in electrodialysis process. Besides the fundamental and benchtop experimental investigation, we are also interested in the implementation of such a membrane system in treating greenhouse irrigation water.
