Graphene oxide was used as efficient adsorbent for the rapid removal of Malachite Green from the aqueous phase, the whole adsorption process was well investigated and elucidated. The impact of several influential parameters such as contact time, initial dye concentrations, initial solution pH and temperature was well studied and optimized. The optimized time for adsorption process was 100 min. The maximum removal efficiency occurred at optimized pH 3 of aqueous solutions. Increasing the initial concentration of Malachite Green dye adsorption capacity was decreased, this may be due to repulsion between Malachite Green negative charge and the graphene oxide surface negative charge. The effect of temperature revealed that adsorption process of dye on the developed adsorbent was endothermic. The adsorption equilibrium data of Malachite Green dye on to the GO adsorbent surface were found to be well fitted and in good agreement with the Temkin Isotherm; because it possesses high value of linear regression (R2 = 0.996) and least value for chi-square statistic (X2 = 2.28).
