This study compares the effects of nonthermal plasma treatment on quinine water solutions for two configurations—the corona-like discharge and the gliding arc discharge (GAD). Different electrolytes were added to the quinine solutions to modify the initial pH and enhance electrical conductivity for plasma discharge ignition directly in the liquid. A slightly higher quinine decomposition rate of 2.9 μg W−1 after 5 min of the treatment was achieved by GAD. From measured spectra, it was found that the absorption maximum at 332 nm was split into two separated peaks in the acidic and basic solution. The study of the time stability of quinine solutions has revealed quinine instability and that postpreparation time has influenced the plasma treatment effect.

血浆对奎宁溶液影响的研究
本研究比较了非热等离子体处理对两种配置的奎宁水溶液的影响——类电晕放电和滑动电弧放电 (GAD)。将不同的电解质添加到奎宁溶液中以改变初始 pH 值并增强直接在液体中进行等离子体放电点火的电导率。在处理5分钟后，通过GAD实现了略高的2.9μg W -1的奎宁分解率。从测量光谱中发现，在酸性和碱性溶液中，332 nm 处的最大吸收峰被分成两个分离的峰。对奎宁溶液时间稳定性的研究揭示了奎宁的不稳定性，并且后制备时间影响了等离子体处理效果。
