Sorption behaviors of propranolol (PRO) on montmorillonite and kaolinite in the presence of fulvic acid (FA) and humic acid (HA) were investigated. Complexation of propranolol with FA/HA also have been studied using the fluorescence quenching method. PRO could be complexed by FA and HA strongly in the 5-9 pH range. PRO sorption was found to be higher on montmorillonite than on kaolinite. In the presence of FA/HA, the sorption of PRO on montmorillonite and kaolinite was inhibited and enhanced respectively. The mechanism is due to the free PRO and complexed PRO has different affinity to montmorillonite and kaolinite surfaces.
