Summary, etc. Zinc oxide nanoparticles and cellulose acetate composite have been synthesized using the in-situ co-precipitation technique and characterized using Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) analyses. The nanocomposite has been used as the adsorbent for the removal of Orange II dye from aqueous solution through adsorptive mechanism. The effect of concentration, <em>p</em>H, time contact, adsorbent dosage and temperature are investigated, and maximum percentage removal of the dye is calculated to be 83%. The Langmuir and Freundlich isotherm model gave a positive result with the adsorption experimental data with value of b and n equal to 0.075 and 1.197 respectively while regression coefficient R<sup>2</sup> equal to 0.839 and 0.859 in each case. The thermodynamics studies of the adsorption show that the adsorption reaction is exothermic and the process follows a pseudo second order kinetic model.
