Sumac Leaves (Rhus Coriaria L), was investigated as an low cost and effective biomass adsorbent for the adsorption of Basic Blue 3 (BB3) from aqueous solution. The effects of initial dye concentration, initial solution pH and phases contact time of BB3 adsorption by biomass were investigated. Rather high dye amount was leached at the begining (5 min.) and the system reached the equilibrium in 30 minutes. Langmuir, Freundlich and Temkin isotherms were applied for defiming the adsorption. Langmuir and Temkin was represented the system rather well. The calculated biomass capacity was 4.01 mg/g. This value was evaluated with the adsorption capacities of some other experimental materials. Pseudo first, second and intra particle diffusion kinetics were applied for describing the sorption phenomenon. Pseudo second order and intra particle kinetics were found to be very effective during the experiment. The chemisorption adsorption is spontaneous and exothermic.
