Adsorption of methylene blue biomass of Prunus cerasus is conducted in batch mode. The effect of various factors such as contact time, adsorbent dosage, initial dye concentration, temperature and pH of dye solution was investigated. The maximum removal of methylene blue dye was attained at 8.0 pH. The adsorption equilibrium was represented with Langmuir, Freundlich and Temkin isotherm models. Langmuir and Tempkin equations were found to have the correlation coefficient value in good agreement. Adsorption of MB onto prunus cerasus followed pseudo second order kinetics. The calculated values of ΔH°, ΔS° and ΔG° were found to be -31.177kJ/mol, 0.1099 KJ/mol and -63.9722 KJ/mol, respectively. The equilibrium data were also fitted to the Freundlich equation. It was observed that the sorption process is spontaneous and exothermic in nature.
