STUDY OF LITHIUM ION ADSORPTION ON LiMgxMn(2-x)O4 (0 ≤ x ≤ 0.8) ADSORBENTS PREPARED BY THE SOL-GEL METHOD
Downloads
In this work, Al3+- modified LiAlxMn(2-x)O4 was synthesized by the sol-gel method with the partial replacement of manganese in the spinel LiMn2O4 oxide phase with Al3+. The characteristics of LiAlxMn(2-x)O4 (0 ≤ x ≤ 0.8) were studied by X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The dependence of lithium-ion adsorption on the effect of pH, adsorbent dose, time and Li+ concentration was studied.
