Adsorption Thermodynamics, Modeling, and Kinetics Studies for the Removal of Lead Ions Using ZnO Nanorods

In the present investigation, zinc oxide nanorods (ZnO-NR) were synthesized via hydrothermal method using ZnCl2 as a ion precursor in presence of cetyltrimethylammonium bromide. Synthesized ZnO-NR was featured advanced techniques including XRD, PL, SEM, and UV-visible spectroscopy. The role these assynthesized evaluated for sequestration lead ions batch mode. elimination achieved at pH 6-7 0.06 g adsorbent dose, 25 min contact time, mg/L initial concentration, 323 K temperature, 200 rpm agitation speed. A thermodynamic study revealed endothermic nature onto ZnO-NR. followed kinetic (pseudo-second-order) isotherm (Langmuir) models. eliminated up to 142 mg/g optimum level affecting variables. might be potential removal from industrial effluents.
