摘要：
The present investigation is on the application of green synthesized CuO nanoparticles for elimination of lead (II) from wastewater. Nano CuO was prepared from aqueous copper acetate solution and aqueous leaf extract of Simarouba glauca plant. The prepared nano CuO was characterized by XRD, FT-IR, UV, SEM and TEM. The nano CuO synthesized by this method was spherical in shape with particle size nearly 20 nm. The adsorption of lead (II) ions on nano CuO under various parameters such as amount of catalyst, concentration of metal ion and pH were studied using Batch adsorption experiments. Experimental results indicate that the green synthesized CuO nanoparticle is a very good adsorbent for the efficient removal of lead (II) from wastewater. Optimum conditions for 95% adsorption of Pb2+. on CuO nanoparticle is pH 6, amount of catalyst 0.05 g and concentration of metal ion 10 mgL(-1).
