Abstract: An underwater capillary plasma device having a gas channel is provided. The underwater capillary plasma device includes a power supply unit configured to supply a power source, a discharge electrode configured to receive the power source supplied from the power supply unit and induce capillary plasma discharge inside a fluid, and a gas supply unit configured to inject an auxiliary gas into the discharge electrode. Since the underwater capillary plasma discharge electrode is equipped with a gas channel, plasma species can be generated from water decomposition caused by plasma discharge, and various chemical reactive species can be generated according to the injected auxiliary gas, thereby effectively removing underwater pollutants. Also, when a gas is injected as described herein, the reactive species generated by the plasma discharge can be increased in concentration and lifetime in the fluid so that a purification effect using plasma can be maximized. Further, when the auxiliary gas is supplied as described above, plasma can be generated even by a smaller supply of power, compared with when the auxiliary gas is not injected, thereby reducing energy consumption for purification of the fluid.
