Efficient Recovery of Lithium from Shale Gas Wastewater: Fe, Ni, and Al Doping of H1.33mn1.67o4 for Improved Adsorption Capacity and Manganese Loss Reduction

Published: Jan. 1, 2024

To minimize manganese loss during acid leaching and to enhance the lithium adsorption capacity of H1.33Mn1.67O4 from shale gas wastewater, this adsorbent material was doped with metallic elements in study. Doping achieved using solid-phase synthesis, resulting first Li1.33RXMn1.67−XO4 (R = Fe, Ni, Al) powder through high-temperature calcination. Then, leached out under acidic environment obtain H1.33RXMn1.67−XO4 (HMO-R) adsorbents. The equilibrium capacities HMO-R powders were measured as 20.7 mg/g, 29.0 for Al dopants, respectively, surpassing that former (13.7 mg/L). Moreover, an average reduction by 30% observed recovery/extraction compared undoped Li1.33Mn1.67O4. Overall, exhibited a stable crystal structure high capacity, enhanced stability, performance, efficiency cycling experiments respect material.
