摘要：

A dielectric barrier discharge plasma reactor was applied to the degradation of tetracycline hydrochloride in the aqueous solution. A series of parameters including input power, air-gap distance, initial concentration and air flow rate were investigated for their effects on the degradation efficiency. The results showed that the degradation efficiency was as high as 92% at the optimum degradation parameters: input power 1.3 W, air-gap distance 2.5 mm, air flow rate 150 ml•min-1, tetracycline hydrochloride initial concentration 100 mg•L-1 and treatment time 30 min. The kinetic studies indicated that the degradation of tetracycline hydrochloride followed the pseudo-second-order kinetics. Based on the intermediate products identified by LC-MS, a possible degradation pathway of tetracycline hydrochloride was proposed. © All Right Reserved.
