Humic acid and ZnO nanoparticles were prepared from HA and ZnO by a paralysis method and characterized. The adsorption of toxic heavy metals, Hg(II), Pb(II), Cd(II), Ni(II), and Cu(II) was studied using synthetic solutions and was reported elsewhere. The adsorption of toxic heavy metals from industrial wastewaters onto the surface of Humic acid coated with ZnO nanoparticles was studied here. The percent adsorption increased with increase in pH from 4 to 6 and remained constant up to 10. As HA and ZnO are commonly available at economical price in market, the resulting Humic acid ZnO nano particles is expected to be an economical product for the removal of toxic heavy metals from industrial waste waters. Polluted water containing contaminants adversely affects its PH value, creating it inappropriate for use. Inorganic substances such as solvents, heavy metals, metal ions, and ammonia rear gases and proteins, organic debris, plant material, food, nitrate, and a variety of other contaminants are hazards substances that contaminate the water in shallow and overwater. The current study deals with the removal of heavy metals from polluted water using the process of bio sorption. ZnO nanoparticles-humid acid hybrid was used as an adsorbent for the removal of nickel (Ni) from the industrial wastewater. The synthesized adsorbent was characterized by FT-IR (Fourier Transform Infrared Spectroscopy), UV/VIS spectroscopy techniques. During this study effect of adsorbent dose, pH, initial metal ion concentration, contact time and temperature were investigated to obtain optimum conditions.
