| Abstract |
Chemically treated activated carbon (CAC) decorated with manganese dioxide (MnO2) was prepared using different Mn salt concentrations as a facile impregnation approach for enhancing the capacity of activated carbon for lithium adsorption. The morphological and physico-chemical properties were characterized. A batch experiment was performed to optimize the parameters (pH, adsorbent dose, and contact time) for Li+ adsorption. A kinetic study indicated that lithium sorption process followed a pseudo-second order reaction. Comparative analysis showed that adsorption capacity of the functionalized activated carbon with various manganese contents increased with an increase in manganese loading, CAC-Mn0.1, CAC-Mn0.12, CAC-Mn0.15, and CAC-Mn0.2, with values of 54%, 70%, 75%, and 96%, respectively. A desorption study was performed to make process more efficient. Overall, it is concluded that the synthesized nanocomposites can be effectively used in lithium adsorption and recovery from aqueous solution.
