摘要：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..
