Suitable organoclays for removing slightly soluble organics from aqueous solutions

Abstract : The adsorption capacity of organo-bentonite towards slightly soluble in water organic compounds of different polarity was studied. The organic solutes were chlorobenzene, toluene and nitrotoluene. The adsorbent were the natural bentonite, the bentonite modified by Na+ ion exchange and organo-bentonites intercalated with hexadecyltrimethyl ammonium, HDTMA, dimethylformamide, DMF, and dimethylsulfoxyde, DMSO. All adsorbent were characterized with the FTIR spectroscopy, XRD and TGA. Experimental results obtained make it possible to acquire a better comprehension of the adsorption mechanism and may be used to improve designing of suitable organo-bentonites for adsorption processes
