The activated carbon was prepared from Albizia saman seed shell using Sulphuric acid. Removal of Naphthol green B (NGB) was assessed by varying the parameter like pH, adsorbent dose, concentration, contact time and temperature. The adsorption efficiency of the prepared activated carbon was estimated by using various isotherm and kinetic equations. The isotherm parameters of the process were determined by using Langmuir and Freundlich isotherm equations. The kinetic parameters were predicted with pseudo first order and pseudo second order equations. Thermodynamic parameters were calculated and it was found that the adsorption of Naphthol Green B (NGB) dye using Albizia saman seed shell carbon (ASSSC) was endothermic and adsorption process. The adsorbent material characterization was done by using Fourier Transform Infrared Spectroscopy (FTIR) and morphology of the surface of adsorbent was identified with Scanning Electron Microscope (SEM).
