The Performance of the CTMAB-DTPA Modified Bentonite as a Sorbent for Cu2+, Cd2+ and Phenol

摘要：

　　CTMAB-DTPA-bentonite (hexadecyl trimethyl ammonium bromide-diethylene triamine pentaacetic acidbentonite) was synthesized by placing alkylammonium cation and organic chelating agents onto bentonite.The simultaneous adsorption of organic pollutant (phenol) and heavy metals (Cu2+ and Cd2+) mixed contaminant on CTMAB-DTPAbentonite was investigated.The CTMAB-DTPA-bentonite showed significant adsorption for the mixed contaminant from aqueouss solution.The Langmuir and Freundlich isotherm equations were applied to the data and values of parameters of these isotherm equations were evaluated.
