Residual detergents and surfactants on utensils have brought about health issues because they can be absorbed to human digestion system together with containing foods. In the present study, a dielectric barrier discharge plasma (DBDP) was used to explore the applicability of non-thermal plasma for the degradation of residual surfactants and dishwashing detergents in order to reduce the intake of the residues remaining on utensils as the result of incomplete rinsing during dishwashing procedures. DBDP was generated at current intensity 2.0 - 3.0 A, and electrode gap 2.5 mm. Diluted dishwashing detergents and surfactants were spotted on slide glasses and exposed to DBDP for different periods of time. The results indicated that the dishwashing detergents and surfactants were degraded by 46.9 - 84.3% after up to 120 min treatments. Weibull equation was the best fit model to the degradation patterns of surfactants, and the decimal degradation time(δ) of 180.2 - 688.9 min were observed according to currents. Surfactants contained in detergents were degraded more effectively than the surfactants themselves. Among the anion surfactants, DDBS was more rapidly degraded than LAS and ABS.
