The adsorption behavior of Naphthol Green B dye from aqueous solution was investigated using Casuarina equisetifolia bark carbon. The effect of various experimental factors such as pH, adsorbent dose, initial dye concentration, contact time and temperature were studied by using the batch technique. The adsorption capacities were evaluated by using Langmuir and Freunlich adsorption isotherm models. Thermodynamic parameters were calculated and it was found that the adsorption of Naphthol Green B (NGB) dye using Casuarina equisetifolia bark carbon (CEBC) was endothermic and adsorption process. Pseudo first order, Pseudo second order and intra particle diffusion models were also used to describe the kinetic data.
