A new atmospheric pressure glow discharge (APGD) plasma‐reaction system generated between a flowing liquid electrode and an Ar microjet nozzle is applied to decompose various organic dyes. The APGD system is working in a flow‐through mode in an open to air atmosphere. Degradation of the organic dyes and formation of reactive oxide and nitrogen species in the liquid and plasma‐liquid interface zone are studied. Effectiveness of this system in decomposition of the organic dyes is also compared with that achieved for the classical advances oxidation processes (AOPs), based on the reaction with H 2 O 2 and with a mixture of H 2 O 2 with F e 2 +ions. The results obtained here indicate that the examined APGD system is very promising for efficient degradation of organic dyes.
