“…The potential range explored varied between )1.5 and 1.8 V, in order to include the hydrogen and oxygen evolution processes [23]. From these voltammograms it is evident that a shoulder, conceivably due to chlorine evolution [24], appears before oxygen evolution and no process attributable to direct oxidation is evident, or is not clearly visible due to low concentration of single contaminants. These results support the hypothesis about the involvement of indirect electro-oxidation as the main mechanism of destruction of the pollutants.…”

The paper is aimed at defining the best option of a combination of electrochemical and biological processes for tannery wastewater treatment. Kinetic data for the electrochemical process are derived from an extensive experimental study, while those relating to biological processes are taken from the authors' previously published studies or from the literature. Four different options based on a combination of electrochemical oxidation and biological treatment are defined and compared with the traditional tannery wastewater treatment with respect to the total required volume, energy need and the quantity of generated sludge.

“…1), the continuously perfused salt (NaCl) solution reacts at the anode surface, producing mainly chlorine and oxygen, but also other reactive oxidants which are released into the bulk fluid. This is dependent on the redox reactions of strongly adsorbed electro-active water-derived intermediate molecular species [19][20][21][22], and a large scientific body of evidence now exists for these processes [15,16,23,24]. This reaction is pH-dependent and (according to the Nernst equation) dictates which free form of chlorine is most prevalent within generated solution; Cl 2 , HClO or ClO [25,26].…”

Due to the limitations associated with the use of existing biocidal agents, there is a need to explore new methods of disinfection to help maintain effective bioburden control, especially within the healthcare environment. The transformation of low mineral salt solutions into an activated metastable state, by electrochemical unipolar action, produces a solution containing a variety of oxidants, including hypochlorous acid, free chlorine and free radicals, known to possess antimicrobial properties. Electrochemically activated solutions (ECAS) have been shown to have broad-spectrum antimicrobial activity, and have the potential to be widely adopted within the healthcare environment due to low-cost raw material requirements and ease of production (either remotely or in situ). Numerous studies have found ECAS to be highly efficacious, as both a novel environmental decontaminant and a topical treatment agent (with low accompanying toxicity), but they are still not in widespread use, particularly within the healthcare environment. This review provides an overview of the scientific evidence for the mode of action, antimicrobial spectrum and potential healthcare-related applications of ECAS, providing an insight into these novel yet seldom utilised biocides.

“…As generally accepted, the direct catalytic oxidation ability of metal oxide anode closely depended on the valence of the metal and the nature of oxidant adsorbed on the electrodes [11][12][13]. The scheme of this mechanism was shown as the following:…”

“…According to literature, Eq. (5) was identified as the rate determining reaction [13]. Since the precious metals in RuO x -PdO-TiO 2 /Ti were with more positive charge and the lattice defect in TiO 2 was increased by the doping of precious metals, the adsorption of Cl − on the electrode surface would be favored, which resulted in the lower potential of chlorine evolution.…”
