제목 Combination of wet-scrubbing and electrochemical generation of homogeneous Ni(I) electron mediator expedites sustainable removal SF6 at ambient temperature
초록 The most recalcitrant SF6 removal is in infancy and deserved for more investigations. This work reports sustainable ambient temperature removal of SF6 using homogeneous Ni(I) electron mediator by mediated electrochemical reduction at electro-scrubbing process. First, [Ni(I)(CN)4]3- (Ni(I)) was generated by paired electrolysis at cathodic half-cell in 10 M KOH solution. The concentration of electrogenerated Ni(I) was derived from potentiometric titration and optimized conditions for high efficiency. The electrogenerated Ni(I) pumped on the scrubber column to remove the SF6 which was entered under the wet scrubbing column. The removal of SF6 was monitored by online FTIR gas analyzer which was attached to the column exit. The feed concentration and gas flow rate effect were analyzed on SF6 removal and discussed.
