Calcined eggshell (CES) was modified with Pluronic 123 (P123), Pluronic 127 (F127) and polyethylene glycol
(PEG) agents and used in adsorption of Remazol Yellow. The adsorbents were
characterized by Fourier transform infrared (FTIR) and scanning electron
microscopy/energy dispersive X-ray spectroscopy (SEM/EDX). FTIR spectrums
showed that characteristic peaks corresponding to CES and modifier agents were
observed and CES was successfully modified. Modification of CES with PEG having
high chain length (or high molecular weight) was positively affected particle
size. From EDX analysis was determined the carbon
content increased from 21.44 % to 36.60 % whereas the calcium content decreased
from 21.23 % to 8.69 % with increasing of the molecular weight of modifier agents.
Removal percent of Remazol Yellow was found
as 91.79, 93.09 and 95.69 for CES-P123, CES-F127 and
CES-PEG, respectively. CES-PEG was adsorbed Remazol Yellow more than other adsorbents. Particle size and carbon
content of adsorbents was more effective in adsorption of Remazol Yellow.
