In the technological processes requiring mild treatment, such as soft materials processing or medical applications, an important role is played by non-equilibrium plasma reactors with dielectric barrier discharge (DBD), that when generated in noble gases allows for the effective treatment of biological material at a low temperature. The aim of this study is to determine the operating parameters of an atmospheric pressure, radio-frequency DBD plasma jet reactor for the precise treatment of biological materials. The tested parameters were the shape of the discharge (its length and volume), current and voltage signals, as well as the power consumed by the reactor for various composition and flow rates of the working gas. To determine the applicability in medicine, the temperature, pH, concentrations of HO, NO and NO and log reduction in the plasma treated liquids were determined. The obtained results show that for certain operating parameters, a narrow shape of plasma stream can generate significant amounts of HO, allowing for the mild decontamination of bacteria at a relatively low power of the system, safe for the treatment of biological materials.
在诸如软材料加工或医学应用等需要温和处理的工艺过程中，具有介质阻挡放电（DBD）的非平衡等离子体反应器发挥着重要作用，当在稀有气体中产生时，它能够在低温下有效地处理生物材料。本研究的目的是确定用于精确处理生物材料的大气压射频DBD等离子体射流反应器的运行参数。测试的参数包括放电形状（其长度和体积）、电流和电压信号，以及反应器在工作气体的各种组成和流速下消耗的功率。为了确定其在医学上的适用性，测定了经等离子体处理液体的温度、pH值、HO、NO和NO的浓度以及对数减少量。所得结果表明，对于某些运行参数，狭窄形状的等离子体流可以产生大量的HO，从而在系统相对较低的功率下实现对细菌的温和去污，这对生物材料的处理是安全的。
