The study demonstrates that Nanocomposite activated Carbone decorated zinc oxide is indeed viable, cost effective adsorbent materials for the adsorptive removal of Reactive Green (RG) dye from polluted wastewater with over 90% removal dye. The adsorption of RG dye onto decorated carbon ZnO nanoparticle was found to be highly dependent on equilibrium time, initial RG dye concentration, adsorbent mass and. The quantity of RG dye uptake (mgg-1) was found to rise through increase in primary dye concentration. Percent removal of RG dye was found to increase with increase in contact time, adsorbent amount. The data indicated that the model Freundlich gave a better fit to the experimental result than the model Langmuir with high correlation coefficients (R2 = 0.964). This suggests that multi-layer adsorption occurs which is in agreement with the best applicability of the isotherm Freundlich.
