The total reduction of Cr(VI) by microsecond pin-to-pin electric discharge generated in aqueous solution has been reported. [Cr(VI)] and [H₂O₂] were measured simultaneously by UV–Vis absorption spectroscopy during the process. The kinetics of the Cr(VI) reduction resulting from the discharges is found to be pseudo zero order rate. The influence of the electron properties has been studied by varying the applied voltage and the electrode gap showing a better reduction for a higher electric field. In addition pH and conductivity of the solution have been measured before and after the process. The analysis of the chemical kinetics has been completed by varying the pulse duration of the discharge. The results show that the reduction occurs both during the plasma and the post plasma phases. It is also noted that the increase of the pulse duration involves a better Cr(VI) reduction, a higher [H₂O₂] production and a more important change in conductivity.

已经报道了通过在水溶液中产生的微秒针对针放电对 Cr(VI) 的总还原。[Cr(VI)]和[H ₂ O ₂] 在此过程中通过紫外-可见吸收光谱同时测量。由放电引起的 Cr(VI) 还原动力学被发现是伪零级速率。已经通过改变施加的电压和电极间隙来研究电子特性的影响，显示出对于较高电场的更好的减少。此外，在工艺前后测量了溶液的 pH 值和电导率。通过改变放电的脉冲持续时间完成了化学动力学分析。结果表明，还原发生在等离子和等离子后阶段。还应注意，脉冲持续时间的增加涉及更好的 Cr(VI) 还原，更高的 [H ₂ O ₂] 生产和电导率的更重要变化。
