Özet

In this study, Remazol Black B dyestuff removal from wastewater by ion exchange was investigated with in a batch system and 2(3) full factorial design was applied. Anion exchanger resin was prepared from agricultural residue (straw) after reaction with epichlorohydrin and dimethylamine in the presence of pyridine and N,N-dimethylformamide (EDM method). The effect of individual variables and their interactional effects for dyestuff sorption were determined. From the statistical analysis, the most important parameter which is efficient in dyestuff removal can be obtained to be initial concentration of wastewater, which is followed by initial concentration-initial pH of wastewater. The interaction between initial pH and temperature was the least important factor for dyestuff removal from wastewater. A series of isotherm studies were undertaken, and the data evaluated for compliance with the Langmuir and Freundlich isotherm models.
