Abstract New LD-ZAO-NPs was facilely synthesized and characterized by FESEM, XRD, EDX and FT-IR. Under the optimal conditions, the MO removal efficiency reached 99.60% after 30 min, Langmuir isotherm and a pseudo second-order kinetic model showed high performance. The thermodynamic parameters showed that the adsorption was spontaneous and favorable as ΔG 0 is negative and exothermic in nature as ΔH 0 is negative (−0.025 kJ/mol). The maximum adsorption capacity (qmax) in single component system 200 mg g −1 for MO supports high efficiency of LD-ZAO-NPs as new adsorbent. Altogether, the superior performance of LD-ZAO-NPs was manifested by fast kinetics and high adsorption capacity.
