Abstract

In this study, treatment of
greywater from laundry washing was investigated by adsorption process with the
use of different waste material derived adsorbents. To synthesize the
adsorbents, walnut shell, seed hull, hazelnut shell and rice husk were
carbonized and then supported with polyaniline. KIO₃ and K₂S₂O₈
were used as oxidizing agents in the polymerization of aniline monomers.
Wastewater treatment efficiencies were evaluated in terms of turbidity, color
and MBAS (detergent) parameters. Adsorption experiments were conducted with 100
mL of wastewater and 1 g of adsorbent, for 2 h of reaction time, at room
temperature and mixing speed of 150 rpm. As a result of studies with different
oxidizing agents; the highest removal efficiencies were calculated for the
PAn/RH+KIO₃ adsorbent as 98%, 70% and 96% for color, turbidity and
detergent, respectively, while for the PAn/SH+K₂S₂O₈
adsorbent they were 58%, 3% and 95% for the same
parameters.
