Acid-generating effect of plasma species and pulsed ultraviolet plasma radiation

Resumo

The yield of acid residues generated in water at pH 3–13 by pulsed plasma radiation of spark discharge with a power of 0.59 W has been studied. The power per pulse of electrical discharge has been optimized to obtain the maximum chemical effect in water. The results are compared with similar data obtained by treatment with 900-W gliding discharge. It has been found that the energy efficiency of pulsed plasma radiation is 100 times that of gliding discharge plasma. The results make it possible to clarify the mechanism of the gliding discharge-induced formation of peroxynitrite.
