The arc is generated in the plasma torch and is hybridly stabilized by water and argon. Gerdien arc features very high plasma temperatures and thus high intensity of short wave ultraviolet radiation. Water (for the arc stabilization) flows at the flow rate of 20 l.min-1 in a thin layer around the arc column. Thus, all water flowing through the torch passes the positions with high level of ultraviolet radiation. Organic compounds such as Orange II, nicotine etc. were used as model compounds whose certain amounts were individually dissolved in a 40 l water system tank before every experiment. The fast decrease of the model compound concentration during first minutes of experiments was observed. Measurements were done by means of UV/Vis spectroscopy and analyses of total carbon, total organic carbon, and total inorganic carbon.
