제목 Selection of Organic Leaching Agent for the Desorption of Li+ from Poly(acrylonitrile)/Manganese Oxide Nanofibrous Membrane
초록 This study evaluates the performance of N,N’,N’-tetramethylethylenediamine (TEMED) and ethylenediaminetetraacetic acid (EDTA) in leaching Li+ ions from saturated poly(acrylonitrile)/manganese oxide (PAN/MO) nanofibrous membrane. Mineral acids, H2SO4, HCl and HNO3 at 2.5 N concentration each, were already tested. HCl exhibited the highest Li+ extraction and eluted Mn. However, low Mn elution is commensurate with preserved structural stability of MO; hence H2SO4 was chosen as the best acid leaching solution over HCl. The optimum organic chelant between TEMED and EDTA would be determined per the Li+ extraction and Mn elution capacities at several adsorption-desorption cycles. This work is supported by the Basic Science Research Program through the National Research Foundation of Korea (NRF) grant funded by the Ministry of Education (No. 2009-0093816).
