Plasma-degradation of the dinitrophenyl (DNP); 2, 4 - DNP, 2, 5 - DNP, 3, 4 – DNP, was studied using a compact dielectric barrier discharge in a quartz tube, immersed into the liquid surface. In the air-plasma treatment, the accumulation of nitric anion was a problem. A simple solution, the anion exchange was found. This process can interrupt the long degradation process to short solution. The exchange of the nitro system of the DNPs was interpreted by the Molecular Orbital Theory.
