This paper summarizes the removal of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) in fly ash obtained from industrial waste incinerators using electrochemically-generated homogeneous Ag(II) ion as a mediator. The initial Ag(II) generation experiment showed higher oxidation efficiency (0.018 M out of the 0.025 M) of Ag(II) at a lower temperature (20 degrees C), which decreases with increasing temperature. Then, the reaction between electrogenerated Ag(II) ion and dioxins was operated at 20 degrees C using a batch reactor for further analysis. First, an experiment examining the removal of a commercial pure 2,3,7,8-TCDD congener solution with a feed concentration of 2.4 ng/L in a batch reactor for a 10 s using electrogenerated Ag(II) revealed 99.75% removal with a resulting concentration of 1.48 pg/L according to high-resolution gas chromatograph/high-resolution mass spectrometry (HRGC/HRMS) analysis (calculated using the UN-EPA method of 1613b). Similar experimental conditions for the removal of fly ash from incinerators with a feed concentration of 58 pg-TEQ/g resulted in 6.68 pg-TEQ/g, which is an approximately 89% removal efficiency for 10 s reaction duration. The developed method is quite promising for the very short time (10 s, first time), removal of dioxins in fly ash from an industrial incinerator. (C) 2015 Elsevier B.V. All rights reserved.
