Arsenic Removal from Arsenic-Bearing Non-Ferrous Metal and Application of Two-Stage Filtration with Fe-Al Porous Material

Xaiowei Tang is an assistant professor of Changsha University of Science and Technology. He graduated with a master's degree from the School of Metallurgy and Environmental Engineering at Central South University, under the supervision of Academician Zhongwei Zhao, and obtained a Ph.D degree from the State Key Laboratory of Powder Metallurgy at Central South University, under the supervision of Professor He Yuehui. His research focuses on Fe-Al porous materials, pore-size gradient Fe-Al filtration materials, and arsenic removal of non-ferrous metals. He developed a new technology for controlling oxygen roasting, joined with two stage filtration based on Fe-Al porous material, and achieved a high effect of arsenic removal. He also developed a deep removal strategy of Cu from Ni Anolyte based on the 285ion-exchange method. He has published over 12 papers in renowned domestic and international academic journals, including Environmental Technology and Innovation, Journal of Environmental Chemical Engineering, Journal of Central South University, and Applied Science.

Yuexiu He is a Changjiang Scholar Distinguished Professor of Central South University and a recipient of the National Science Fund for Distinguished Young Scholars. He is the director of the Powder Metallurgy Subcommittee (SAC/TC243/SC4) of the National Technical Committee for Nonferrous Metals Standardization. His research focuses on Fe-Al porous materials, pore-size gradient TiAl membrane filtration materials, Ti/Al powder-based TiAl alloy thin sheets, Al electrolytic inert cathode materials, novel Ni foam preparation techniques, inert gas atomization for eutectic carbide spherical powder production, and the fundamental research on gradient hard alloy preparation. He presided over the National "973" Basic Research Program and National "863" High-Tech Fund Project. He pioneered the use of Ti and Al elemental powders to prepare homogeneous pore gradient TiAl membrane filter materials, successfully separating TiCl4. He also achieved the first-ever synthesis of tungsten oxide nanocubes, nanowires, and multi-blade nanowires in both domestic and international contexts, inventing the metal-catalyzed method for producing tungsten nanowires. He was awarded the first prize of the National Science and Technology Progress Award (Award No. J-215-1-01).
