摘要：
The luminescent properties of microwave discharge electrodeless mercury lamp (MDEL-Hg) which was ignited within the resonant cavity and photolysis of hydrogen sulfide with low concentration were studied in this paper. Experiment results indicated that the Interior MDEL-Hg could be made the best of energy utilization and the efficiency of photolysis of H2S was very significant under the experimental conditions with the initial H2S concentration of 7.9 mg m(-3). With residence time of 1.5 s, the removal efficiency of hydrogen sulfide was 91%, the absolute removal amount (ARA) was 3.24 mu g s(-1) and the energy consumption was 58.23 mg (kW h)(-1).
