Abstract : Functional sorbent Al-DTPA-CTMAB-bentonite (hydroxyl aluminum-diethylene triamine pentaacetic acid-hexadecyl trimethyl ammonium bromide-bentonite) was synthesized by placing hydroxyl-aluminum pillared agent, alkylammonium cation and organic chelating agents onto bentonite. The simultaneous adsorption of organic pollutant (phenol) and heavy metals (Cd2+) mixed contaminant on Al-DTPA-CTMAB-bentonite was investigated. The Al-DTPA-CTMAB-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.
