The Eucalyptus lenceolata wood was collected from Malakand division, Khyber Pakhtunkhwa Pakistan. Chemical activation of sample conducted for surface efficiency. Batch studies were performed to address various experimental parameters like, contact time, temperature and adsorbent dosage the removal dye. For elemental analysis, morphology identification different functional groups, energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM) Fourier transform infrared (FTIR) techniques applied, respectively. Removal dye (Basic Green 5) studied on raw activated samples by kinetics adsorption at temperature. BET isotherm used characterize area sample. Under conditions investigated, a higher carbonization promoted development porous structures. Intraparticle diffusion, Elovich Bhangam models studies. From kinetic data thermodynamic like ΔH≠, ΔS≠ ΔE≠ determined. results show that is spontaneous process. endothermic nature adsorptive process due positive value enthalpy. negative entropy shows acids molecules take an oriented position. all best fitted these adsorption.
