Abstract

An experimental study of the oxidation of hydrogen sulfide and formaldehyde impurities in humid air by ultraviolet radiation at wavelengths of 184.95 and 253.65 nm has been carried out at a pressure of 1 atm, an initial temperature of 20 °C, a relative humidity of 90%, and a flow rate of the gas mixture of 4920 m
