dc.description.abstract | Lithium recovery by adsorption from aqueous resources is promising with respect to securing finite mineral resources. In this study, an inorganic spinel lithium manganese oxide (LiMn2O4) nanofiber with a tunable diameter was fabricated by electrospinning. Spinel hydrous manganese oxide, which has high lithium selectivity, was derived from LiMn2O4 by Li+-H+ exchange. The kinetic and isotherm studies with respect to Li+ adsorption revealed that the nanofibers fitted well to the second-order kinetic model and the Langmuir adsorption model; moreover, adsorption capacity increased as diameter decreased. The relationship between Li+ adsorption and diameter was explained according to the Brunauer-Emmett-Teller (BET) surface area: Adsorption capacity increases with an increase in BET surface area. Notably, the nanofibers performed better than the particles with the same chemical composition as that of the nanofibers; this trend was attributed to the aggregation of the particles, which caused the number of sorption sites to decrease. The reusability of the nanofiber was assessed through adsorption-desorption cycle tests. The adsorption capacity of the nanofiber with a diameter of 45 nm, which was the smallest diameter, was largely reduced after the five-cycle process; moreover, the capacity only reached 61% of the initial capacity at the fifth cycle, while the other nanofibers and the particle maintained capacities of over 90% at the fifth cycle. This reduction in Li+ adsorption was due to the significant detriment of the fibrous structure during the adsorption-desorption process. The nanofiber with a diameter of 90 nm was optimal in terms of adsorption capacity and reusability. Furthermore, the Li+ selectivity test conducted in artificial sea water showed that Li+ selectivity was the greatest among other cations. | - |
