Recently,a plasma catalyst was employed to efflciently degrade antibiotic residues in the *** this study,the plasma generated in a packed bed dielectric barrier reactor combined with TiO_(2)catalyst is used to degrade the antibiotic tiamulin(TIA)loaded on the surface of simulated soil *** effects of applied voltage,composition of the working gas,gas flow rate and presence or absence of catalyst on the degradation effect were *** was found that plasma and catalyst can produce a synergistic effect under optimal conditions(applied voltage 25 k V,oxygen ratio 1%,gas flow rate 0.6 l min^(-1),treatment time 5 min).The degradation efflciency of the plasma combined with catalyst can reach 78.6%,which is 18.4%higher than that of plasma without *** the applied voltage is 30 k V,the gas flow rate is 1 l min^(-1),the oxygen ratio is 1%and the plasma combined with TiO_(2)catalyst treats the sample for 5 min the degradation efflciency of TIA reached 97%.It can be concluded that a higher applied voltage and longer processing times not only lead to more degradation but also result in a lower energy *** the oxygen ratio and gas flow rate could improve the degradation *** relative distribution and identity of the major TIA degradation product generated was determined by high-performance liquid chromatography–mass spectrometry *** mechanism of TIA removal by plasma and TiO_(2)catalyst was analyzed,and the possible degradation path is discussed.

Recently,packed-bed discharge plasma technologies have been widely studied for treatment of volatile organic compounds(VOCs),due to the good performance in improving the degradation and mineralization of *** this paper,a coaxial cylindrical dielectric barrier discharge reactor packed with porous material of micron-sized pores was used for degradation of benzene,and the discharge characteristics and ozone generation characteristics were *** the discharge length was 12 cm and the filling length was 5 cm,the packed particles in the discharge area significantly increased the number of micro-discharges,and the current amplitude and density increased with the pore size of packed particles,but the discharge power and ozone concentration showed a trend of first increasing and then *** discharge power and ozone production reached the maximum when the size of pore former was 75μm,correspondingly,the degradation efficiency of benzene was the highest.
