Copper oxide nanoparticles were prepared by co precipitation technique and characterized well considering their chemical structure, morphology and adsorption behavior. In this research work, we study the copper oxide nanoparticle’s absorb heavy metals from the surroundings by performing as a sorbent. Heavy metals like cadmium (Cd), and lead (Pb) eradicating from contaminated water during the treatment process. CuO NPs function as an inorganic adsorbent source for the removal of heavy metals. Different variables like varying contact time (t), and different doses of adsorbent (CuO) were studied to find its effect on removal efficiency. Two isotherm models (Langmuir, Freundlich) were tested to determine which adsorption procedure will be followed. In order to determine how time affected the removal process, kinetic tests were looked at. Adsorption of metals Pb and Cd has reached equilibrium after 20 minutes and at a concentration of 0.3g/L. Pseudo second order kinetic reaction has given a realistic description of the removal of Cd and Pb metal ions with the closer value of qe (calculated) and qe (exp). for both metal ions. Cd and Pb metal adsorption on CuO NPs follow Langmuir adsorption isotherm model.
