In this study, a typical organobentonite, cetyltrimethylammonium saturated bentonite(CTMAB-bentonite), was chosen as adsorbent. Aniline (Sw = 34 g/L,
logKow = 0.9) and phenol (Sw= 83 g/L, logKow = 1.46) (Yaws, 1999)
were selected as the model organic contaminants since they were two
typical chemicals that normally exist in industrial wastewater
