A mechanism of hydrogen peroxide (H₂O₂) generation in plasma-activated lactated Ringer’s solution (PAL) has been analyzed. PAL was produced by irradiating a sodium lactate solution, a class of hydroxy acid, with non-equilibrium atmospheric pressure plasma (NEAPP). The concentration of H₂O₂ generation was dependent on the initial lactate concentrations, which ranged from 0–28 mM. However, the generation of H₂O₂ was inhibited by higher lactate concentration. The formation of H₂O₂ is proposed by catalyzed lactate and radicals in aqueous solution, such as ⋅OH, ⋅H and ⋅OO, during the plasma treatments.

非平衡大气压等离子体辐照乳酸盐溶液中的过氧化氢

已经分析了等离子体激活的乳酸林格氏溶液 (PAL) 中产生过氧化氢 (H ₂ O ₂ )的机制。PAL 是通过用非平衡大气压等离子体 (NEAPP) 照射乳酸钠溶液（一类羟基酸）产生的。H ₂ O ₂生成的浓度取决于初始乳酸浓度，范围为 0-28 mM。然而，H ₂ O ₂的产生受到较高乳酸浓度的抑制。在等离子体处理过程中，H ₂ O ₂的形成是由水溶液中的催化乳酸和自由基（例如 ⋅OH、⋅H 和 ⋅OO）提出的。
