摘要
Electrical discharges in or in contact with liquid can produce H2O2effectively.However,wound treatment requires not only high energy yield,but also low temperature,stability,safety and reproducibility in H2O2generation.Thus a method of producing H2O2in saline solution reacting with He/H2O plasma jet is described in this paper.Two working modes(bullet and arc modes)are stable while keeping at low temperature in the H2O2production.The production is much faster under the arc mode,but has rather high production rate and energy efficiency under the bullet mode.Plus,the energy efficiency increases with treatment time and higher moist helium flow rate under both modes,but especially the bullet mode.Moreover,55 min after the plasma treatment,there is only 6%degradation of H2O2concentration in the saline solution,and this indicates the potential of He/H2O plasma jet in plasma pharmacy.
Electrical discharges in or in contact with liquid can produce H2O2 effectively. However, wound treatment requires not only high energy field, but also low temperature, stability, safety and reproducibility in H2O2 generation. Thus a method of producing H2O2 in saline solution reacting with He/H2O plasma jet is described in this paper. Two working modes （bullet and arc modes） are stable while keeping at low temperature in the H2O2 production. The production is much faster under the arc mode, but has rather high production rate and energy efficiency under the bullet mode. Plus, the energy efficiency increases with treatment time and higher moist helium flow rate under both modes, but especially the bullet mode. Moreover, 55 rain after the plasma treatment, there is only 6% degradation of H2O2 concentration in the saline solution, and this indicates the potential of He/H2O plasma jet in plasma pharmacy.
