Direct valorization of real acid mine drainage into MgAlFe-LDHs: structural evolution, sulfate fixation, and anionic pollutant removal
This study demonstrates a sustainable, anion-free route for directly converting real acid mine drainage into highly crystalline MgAlFe-LDHs that simultaneously fix sulfate and remove dissolved metals, while the resulting functional materials exhibit significant potential for adsorbing subsequent anionic pollutants like methyl orange and Cr(VI).
