The pyrolysis carbon black (CBp) from waste tires contains zinc, iron, and other metal elements, which have high recycling value. This study proposes a simple method of recovering zinc iron tire-derived CBp to synthesize hydrotalcite-type adsorbents for the treatment anodic dye wastewater. Firstly, zinc-aluminum hydrotalcite (LDH) zinc-iron aluminum (FeLDH) were obtained by leaching ions with an acid solution. As compared LDH, FeLDH shows increased laminate ion arrangement density layer spacing. By calcining LDH at 500 °C, oxides (LDO) (FeLDO) then prepared applied adsorption methyl orange (MO). results demonstrate that maximum capacity LDO FeLDO are 304.9 609.8 mg g−1 pH 4.0, respectively. processes both consistent Langmuir isotherm proposed second-order kinetic model. regeneration performance mechanism also investigated in detail. Regeneration experiments show after three cycles, removal rate MO remains above 80%, while only around 64% first cycle regeneration. work would provide new pathway realize high-value solve contamination
