摘要

Nickel Oxide Nanoparticle and Modifying its surface by waste batteries are used to remove methyl orange dye from aqueous solution by adsorption process after its preparation and characterization. Hydrothermal technique was used to synthesize NiO nanoparticles and then coupling with granular activated carbon (GAC) from waste batterie. Surface morphology of the final modified nanocomposite was estimated to be using SEM, XRD, FT-IR and TEM. The elemental contents of the prepared nanocomposite were determined using particle-induced X-ray emission EDX. Using X-ray diffractometry (XRD) the product’s size and phase compositions were determined. The average particle size of the (GAC/NiO) NC was discovered to be (40.49) nm, and it has the potential to be used as an adsorbent to remove methyl orange (MO) dye. The behavior adsorption of GAC, and (GAC/NiO) NC were studied using (MO) dye. The maximum removal (87.09, and 99.8%) of MO onto (GAC, and (GAC/NiO) NC respectively were observed at (pH 2.12 and 3.4), adsorbent amount (0.2 and 0.06) g/40 ml and temperature 25 °C. Thence, on evaluating and optimizing condition, the results exhibited that more than 98% dye removal was reached in first 30 min for (GAC/NiO) NC, while more than 85% of the dye was removed by (GAC) in the first 60 min, the adsorption equilibrium, kinetics, and thermodynamics models were additionally looked at. The outcomes demonstrated that adsorption proceeded in a pseudo-second order, and Langmuir models. The feasibility, endothermic, and spontaneous nature of the MO adsorption on GAC and (GAC/NiO) NC were shown by the thermodynamic assessment.
