Influential factors were investigated to increase decomposition efficiencies of sulfur compounds using an electron beam. Their initial concentrations, different background gases, and relative humidity were of main concern as the factors. Decomposition efficiency of H2S by primary electrons was lower than those of CH3SH, DMS, and DMDS containing one or two CH3 groups. The G-values increased as their initial concentrations increased and the adsorbed dose decreased. Removal efficiencies were highest for H2S and CH3SH in the simultaneous presence of N and O radicals. In contrast, reactions with the O radical were the most effective when DMS and DMDS were irradiated by electron beam under different background gases. Adding water vapor to the reactors resulted in the increase of decomposition efficiency.
