Recovery of lithium ions from seawater using a continuous flow adsorption column packed with granulated chitosan–lithium manganese oxide
Abstract
We demonstrated an efficient recovery of lithium ions (Li + ) from seawater using a continuous flow column packed with an adsorbent, chitosan–lithium manganese oxide (LMO). The effects of Li + concentration, contact time, and recyclability were investigated. The adsorbent showed good removal efficiency of Li + from seawater. The maximum adsorption capacity was calculated to be 54.65 mg/g. The adsorption process fit well with the Freundlich isotherm with a correlation coefficient of 0.9924. Kinetics studies showed that the adsorption process was consistent with the pseudo-second-order model. The recyclability was tested after extraction of Li + from the adsorbent using sulfuric acid. The adsorption capacity decreased slightly after recycling the adsorbent three times. This may be due to the dissolution of Mn 2+ and deformation of the chitosan structure. A study of the selectivity of Li + in seawater showed that the selectivity increased in the order Li + > Mg 2+ > Na + .

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
