In our research group, multi-gas ICP (inductively coupled plasma) source was developed for industrial plasma processing and traced elemental analysis. With the multi-gas ICP source, not only Ar but He, O2, N2, CO2, air and their mixture gas plasmas can be stably generated in atmospheric pressure. In this study, the plasma source was applied for decomposition of anesthetic gas which effect on global warming as involving N2O. N2O/air mixture gas plasma was generated by the plasma source then the composition of treated gas was measured. Effect of the RF input power on decomposition rate of N2O was investigated. As a result, 99.98 % of decomposition rate 99.98 % of decomposition rate and 117 g/kWh of energy efficiency were achieved at 800 W of the RF input power and 1 % of NO2 was generated as a by-product.
