Abstract

Kaolin has been synthesized in the nano-sized (30-60 nm) and examined as a photocatalyst for degradation of tetracycline in its aqueous solution. The photocatalytic behavior was performed under the effect of UV-radiation. The influences of various operational parameters such as catalyst dose, drug concentration, and time of exposure on percentage photodegradation of tetracycline chloride were investigated. The results reveal that the maximum degradation (97%) occurred after about 120 min irradiation. The degradation rate follows first order kinetics with a rate constant of 0.02 min-1.
