We have processed to surface active agents in atmospheric-pressure non-equilibrium plasma. We have measured to absorptive power and pH value of methylene blue solute aqueous to after processing plasma. The existence of OH radicalsin theorganic solute aqueousliquid phase is able topromote the generation of hydroxyl radicals during the degradation process. The methylene blue molecule hasoxidized into inorganic ions by atmospheric-pressure non-equilibrium plasma.
