AI中文摘要:
本研究旨在验证非热平衡大气压等离子体与过氧化苯甲酰(BPO)联合是否能增强细菌抑制效果。研究不仅涉及调整等离子体装置参数,如提高电源电压、改变工作气体流速、向工作气体中加入特定比例氧气,还将等离子体与BPO结合用于细菌灭活。利用发射光谱确定实验装置的最佳工作气体流速和氧气混合比,还进行表面温度和紫外线发射测量以表征等离子体处理的物理性质。虽等离子体与BPO间精确化学机制尚未完全阐明,但对大肠杆菌的灭活实验表明,添加BPO确实增强了等离子体处理的杀菌效果。
英文摘要:
This study aims to verify whether combining non-thermal equilibrium atmospheric pressure plasma with benzoyl peroxide (BPO) can enhance the inhibition of bacteria. This work involves not only adjusting the parameters of the plasma device, such as increasing the power supply voltage, modifying the working gas flow rate, as well as incorporating a specific proportion of oxygen to the working gas, but also aims to combine plasma with BPO to inactivate bacteria. An optical emission spectroscopy was utilized to determine the optimal working gas flow rate and oxygen mixing ratio for the experimental setup. Additionally, surface temperature and ultraviolet (UV) emission measurements were also performed to characterize the physical properties of the plasma treatment. Although the precise chemical mechanisms between plasma and BPO have yet to be fully elucidated, bacterial inactivation experiments on Escherichia coli demonstrated that the addition of BPO indeed enhanced the sterilization efficacy of plasma treatment.
