Abstract: The present work deals with adsorption of Malachite Green (MG) dyes carried out in the presence of Activated Cissus Quadrangularis Stem Nano Carbon (ACQNC). Various parameters like the effect of initial concentration, contact time, dose of adsorbent, temperature and pH were also studied. The result shows that when the amount of adsorbent increases, the percentage removal of dye increases. The applicability of Freundlich adsorption and Langmuir adsorption isotherm had also been tested. Adsorption kinetic data have been tested using pseudo second order, intra-particles models and the Elovich model. The thermodynamics parameter such as Î”G0 Î”H0 and Î”S0 were calculated. The adsorption capacities of Activated Cissus Quadrangularis Stem Nano Carbon (ACQNC) were calculated using batch process
