Textile
and dye industries’ wastewaters are one of the major problem in the water
pollution. This wastewater causes serious environmental pollution, because of
non-biodegradable and toxic dye molecules. Azo dyes are widely used in the
textile industry. In the anaerobic condition azo dyestuff decompose to toxic
byproducts. The aim of this work is to understand the adsorption mechanisms of
various azo dyestuff adsorbed by domestic wastewater treatment plant
inactivated sludge. To determine the adsorption mechanisms, various isotherms and
kinetics were used and constants of each isotherms and kinetics were calculated
for each dyestuff. In this study, Reactive Black 5 (RB5), Reactive Blue 21
(RB21), Acid Brown 283 (AB283) and Basic Violete 3 (BV3) azo dyestuff
adsorption data were used for isotherms and kinetics calculations. The results
of this study showed that, the best isotherm which describe the adsorption
process was Freundlich. This isotherm model assumes that heterogeneous sorption
occurs on adsorbent surface, stated in other words adsorption power varies at
every sorption point. For RB5 and AB283 dyes, the best kinetic model which
describe the adsorption process was pseudo-second-order kinetic model. This
kinetic model assumes that adsorption rate dependent to adsorbent material quantities
and contact time.
