Özet:

 

In this study, hexadecyltrimethylammonium (HDTMA) bentonite was  synthesized by placing alkylammonium cation onto bentonite.   Adsorption of some textile dyes such as Everdirect Supra Yellow PG,  Everdirect Supra Orange 26 CG, Everdirect Supra Rubine BL, Everdirect  Supra Blue 4BL and Everdirect Supra Red BWS on Na-bentonite and  HDTMA-bentonite was investigated.  While the Na-bentonite had no  affinity for the dyes, the HDTMA-bentonite showed significant  adsorption from aqueous solution.  The Langmuir and   Dubinin-Rasdushkevich (D-R) isotherm equations were applied to the data  and values of parameters of these isotherm equations were evaluated.   The mean energy of adsorption, E, was also calculated from the  adsorption energy constant K' values determined from the D-R isotherm  equation.
