Ca/Al–Cl LDH can efficiently remove the organic matters in stabilized landfill leachate.
The formation of Ca/Al–LDH have a greater beneficial to remove organics than the other reagents.
The removal of fulvic acid-like compounds by Ca/Al–LDH was much better than humic acid-like ones.
Ca/Al–LDH had a selectivity for the removal of compounds with more carboxylic groups.
