ABSTRACT
Textile industry wastewater plays an important role in environmental pollution. In the present study,
the removal of actacid orange-RL (AO-RL) dye was carried out in batch mode with biocomposites. The
optimum pH, biosorbent dose, equilibrium time, initial dye concentration, and temperature for maximum
dye adsorption were recorded in the range of 3-6, 0.05 g, 60 min and 125-150 mg/L and 30ºC, respectively.
Langmuir and Freundlich biosorption isotherms showed the satisfactorily fitness on equilibrium biosorption
data, whereas the pseudo first-order and pseudo second-order both showed the satisfactorily fitness on
biosorption kinetic data. The characterization of efficient biosorbents was carried out using FT-IR and SEM
techniques, which revealed a significant change in biocomposite as a result of dye adsorption. Based on
results, we can conclude that the biocomposite could be an efficient adsorbent for the adsorption of dyes
from textile wastewater.
