Abstract：ClO2 based advanced oxidation process has been widely studied in the field of micropollutant removal， series of reactive species (such as Cl， ClO， 1O2， HO， O3， etc.) produced by ClO2 photolysis are used to degrade target pollutants in water body. Taking the anti-epileptic drug carbamazepine (CBZ) as model pollutant， which is non-biodegradable and non-photodegradable thus durable in water， the roles of reactive species on the CBZ degradation and the degradation pathway were systematically investigated. The water matrix， such as pH and the addition of various substrates (Cl－、HCO3(－)、fulvic acid and humic acid)， on the CBZ degradation was also studied. It’s revealed that 1O2， HO and Cl made great contribution on the CBZ degradation in the simulated sunlight/ClO2 system. The CBZ degradation efficiency decreases with the increase of pH values， the existence of Cl－ does little effect on the CBZ degradation， the presence of HCO3(－) obviously inhibits the CBZ degradation， the CBZ degradation activity decreased more with the addition of humic acid than that of fulvic acid in water， and the cations (K＋/Ca2＋/Mg2＋) did not affect the CBZ degradation.
