••
TL;DR: It is shown that pollutant degradation with the BDD/SO4(2-) and IrO2/Cl(-) systems were better at removing the pollutant, and the former the most effective.

TL;DR: In this paper, a systematic experimental study has been carried out to analyze the influence of the following operation variables: (i) initial THF concentrations in the range 500-1100mg/L, (ii) supporting electrolyte, Na2SO4 and NaCl and (iii) current density in range 300-1200A/m2.

TL;DR: In this paper, the effects of polishing and cleaning, chemical and electrochemical surface treatments, pH, supporting electrolyte cations and anions and time on the redox behavior of the system were systematically evaluated.
Abstract: Detailed cyclic voltammetric studies were carried out on the hexacyanoferrate(II)-hexacyanoferrate(III) redox system in H2SO4, Na2SO4, NaOH, NaCl, KCl, NaH2PO4, Na2C2O4 and trisodium citrate media on a glassy carbon electrode. The effects of polishing and cleaning, chemical and electrochemical surface treatments, pH, supporting electrolyte cations and anions and time on the redox behaviour of the system were systematically evaluated. The following conclusions were drawn: (a) surface polishing or exposure to the atmosphere does not affect the reproducibility of the results; (b) anodic polarisation activates the electrode surface, as found in earlier studies, but some additional evidence indicates that this is due to oxidation of the fresh carbon surface, and this aspect is considered in detail; (c) the rate constants calculated for the oxidation of hexacyanofer-rate(II) and the reduction of hexacyanoferrate(III) using Nicholson's method differ substantially; this is attributed to different surface states of the glassy carbon at the starting potentials; and (d) anions have a substantial effect on both the rate constants and the limiting currents; chloride ions have a special activating effect. These effects are discussed on the basis of adsorption and mediated electron transfer. Other factors that influence the electron-transfer kinetics such as time effects and heat-treatment temperature are also discussed.

TL;DR: The results are consistent with a mechanism where PQ(2+) binds negatively charged groups of HA (carboxylates and phenolates) forming ionic pairs or outer-sphere complexes, which may act as a good adsorbent for cationic herbicides.
