Özet

In this study, the removal of organic contaminants from wastewater has been studied by using hexadecyltrimethylammonium bentonite (HDTMA-bentonite). HDTMA-bentonite was synthesized by placing quaternary ammonium surfactant (hexadecyltrimethylammonium bromide) on the sodium bentonite (Na-B) by cation exchange. The sorption of organic pollutants was examined by batch equilibration method at 25 degrees C. As organic contaminants polar compounds (methylene blue, benzoic acid and salicylic acid) and nonpolar compounds (toluene and xylene) were used. The concentrations of the organic pollutants used ranged from 0 to 700 mg/L. Methylene blue, benzoic acid and salicylic acid sorptions to HDTMA-bentonite were characterized by relatively strong solute uptake. Toluene and xylene sorptions to HDTMA-bentonite were weaker.
