Abstract
An experimental study was performed to investigate the feasibility of using cetyltrimethyl ammonium bromide (CTMAB) and N-2-hydroxypropyl trimethyl ammonium chloride chitosan (HTCC) bentonite (CTMAB–HTCC bentonite) for simultaneous sorption of phenol and Cd(II). The preparation of CTMAB–HTCC bentonite was listed as follows: for bentonite (5 g), 1.0 g CTMAB and 0.2 g HTCC was adopted as the modifying reagents; the reaction was carried out for 2 h at 60°C. The role of competition between phenol and Cd(II) was studied. The sorption of Cd(II) onto CTMAB–HTCC bentonite decreased in the presence of phenol relative to the sorption obtained without phenol presence. This decrease resulted from the steric hindrance caused by phenol. The sorption of phenol onto CTMAB–HTCC bentonite in the presence of Cd(II) was less than the sorption observed when no Cd(II) was present. This decrease was attributed to the formation of complex between Π-electron in phenol and Cd(II), which was unfavorable for the adsorption of phenol onto CTMAB–HTCC bentonite by partitioning mechanism. Although sorption was decreased in the presence of the other, CTMAB–HTCC bentonite tested had dual sorptive properties for both heavy metals and an organic contaminant.
