Title: Recent Development of Cation-exchange Stationary Phases for the Separation of Rare Earth Ions

Hongdeng Qiu received his PhD from Lanzhou Institute of Chemical Physics (LICP), Chinese Academy of Sciences (2008). He did his postdoctoral research in Kumamoto University from 2009-2012 (including JSPS Fellow). From 2012-2023, he was a full professor in LICP. Then he moved to Ganjiang Innovation Academy, Chinese Academy of Sciences and become a part time professor in LICP. His current research interests are the applications of new materials for chromatographic separation and sample preparation, especially for rare earth ion separation. He has published more than 270 papers and 50 patents.
