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.
