摘要: The absorption of nitric oxide (NO) into water with simultaneous oxidation induced by ultrasonic irradiation at a fixed frequency 20 kHz has been studied in bubble column reactor about room temperature. Factors include the flow rate flue gas, intensity ultrasound, and effect sulfur dioxide (SO2) on fractional conversion NO. concentration NO inlet gas ranged from 50 to 1040 ppm, while that SO2 52 4930 ppm. conversions were found range 60% 85%, complete removal was observed for all concentrations studied. In addition, presence low moderate stream enhance removal. Also, increasing improve Sonochemical pathways leading nitrite, nitrate, sulfate formation are discussed. results this study suggest feasibility developing an innovat...
