vermiculite and diphenyl

Two novel biphenyl and dipyridyl gemini surfactants, bis-N, N, N,-hexadecyldimethyl-p-biphenylenediammonium dichloride (BHBP) and 1,1'-dihexadecyl-4,4'-bispyridinium bromide (DHBP) were designed and used to functionalize the high layer charged vermiculite (Vt) for the first time. Key organo-Vt characteristics, such as the modifier loading, arrangement and the stacking unit of platelets were specified by FT-IR, XRD, TG, SEM and Elemental Analysis. The saturated surfactant dosage in the modification process, in reverse relationship with the availability of the modifier, was defined as low as 0.4 CEC of Vt. The adsorption performance of organo-Vts were tested by bisphenol A (BPA), which showed great potential as organic adsorbents (143.5 mg g
