Adsorption isotherm Study of Cu (II) and Ni (II) on commercial zinc oxide nanoparticle

In this study, commercial zinc oxide nanoparticles were used. Various techniques such as AFM, XRD, and FTIR employed to characterize their surface studies. From the XRD analysis, each reflection peak with relative intensity of different planes determined presence ZnO spectrum revealed that particle size was about (27.43 nm), which is in good agreement those estimated from AFM analysis. It showed diameters are nanometer range. This used separate copper (II) nickel ions aqueous solutions via batch adsorption method. The effect contact time, adsorbent dose, initial concentration, temperature studied. has been found relation between increasing concentration metal percentage opposite. removal 96.45% 96.02% for Cu Ni respectively. Finally, thermodynamic parameters calculated. values functions process (∆H, ∆G, ∆S) indicate exothermic, spontaneous, less random when overlap nanometal oxides. also noted Freundlich Halsey isotherms best describing removing on compared other Langmuir Elovich isotherms.
