제목 Development of high capacity Li+ adsorbents from H2TiO3/polymer nanofiber composites: Systematic polymer screening, characterization and evaluation
초록 Various polymers were systematically screened as matrix for H2TiO3 as Li+ adsorbent. H2TiO3/polymers were electrospun as nanofiber (NF) composites, characterized, and evaluated via response surface methodology with central composite design of Li+ adsorption experiments. Results identified polyacrylonitrile (PAN) as the most suitable H2TiO3 support. Its favorable NF structure and hydrophilicity provided sufficient H2TiO3/PAN-feed interaction, which minimized losses in Li+ adsorption rate and capacity (q) relative to H2TiO3. Li+ adsorption in H2TiO3/PAN is Langmuir-type (qmaximum = 72.75 mg g-1), highly selective, and thermodynamically favorable. Stable performance and durability during cycled adsorption/desorption run prove H2TiO3/PAN NF as a highly effective composite Li+ adsorbent. This research was supported by Basic Science Research Program through the National Research Foundation of Korea(NRF) funded by the Ministry of Education(2018R1D1A1B07048007 and 2009-0093816) and by the Ministry of Science and ICT (No. 2017R1A2B2002109).
