Only TC showed significant adsorption to natural montmorillonite and rectorite, whereas CAP and SMX adsorbed to natural montmorillonite, kaolinite and rectorite to a much lower extent. The adsorption equilibrium constants (L/kg) of TC to natural montmorillonite were 332 and 108 at pH 3.0 and 7.0, respectively. The kinetic rate constant k app (min−1) for the removal of CAP in the presence of different clay minerals follows the sequence: montmorillonite KSF (1.6×10−2)>rectorite (4.6×10−3)>natural montmorillonite (3.8×10−3)>kaolinite (2.8×10−3). Removal of SMX follows the same sequence. Oxalate significantly promotes the removal of CAP and SMX in montmorillonite KSF dispersion, while penicillamine (PEN) and β-cyclodextrin retard the diminution. After 3h of irradiation in 5g/L KSF dispersion, the total organic carbon was reduced by 72 and 39% for CAP and SMX, respectively.
