“…In more recent years the electrochemical detection of chlorophenols and the development of an electrochemical sensor for these compounds have been investigated intensively together with their degradation and adsorption [6][7][8]. Different bare electrode materials such as gold, platinum, glassy carbon and boron doped diamond electrodes have been tested [4,[9][10][11][12][13] as well as modified electrodes with different kinds of catalysts [14,15].…”

Because of their toxicity to humans and their tendency to bioaccumulate in the food chain, the detection of chlorophenols has been investigated intensively. This paper compares the oxidation of 4-chlorophenol on a bare gold electrode to its detection on gold electrodes electrochemically modified with either cobalt(II) tetrasulphonated phthalocyanine (CoTSPc) or 3,4 ,4 ,4 -copper(II) tetrasulphonated phthalocyanine (CuTSPc). Results show that the electrochemical behaviour of 4-chlorophenol depends on the molecular structure of the phthalocyanine thin film layers on the gold surface. In addition, the influence of the coordinating properties of the phthalocyanines on the sensitivity of the measurement and the fouling of the electrode material is discussed.

“…For GC, BDD and EG-PS composite, EG-Epoxy composite electrodes the peak current decreases by 64.18%, 13.10%, 58.80%, and respective 54.64%, starting with the second CV. In general, the electrode fouling is owing the complex mechanism of phenols oxidation on carbon based electrode, which involves both the adsorption of reactant/intermediate or final oxidation products and the formation of passive, nonconductive layer of oligomer products of oxidation process on its surface [3,5,11,12].…”

A group of carbon-based electrodes, i.e., glassy-carbon (GC), boron doped diamond (BDD), expanded graphite-polystyrene composite (EG-PS), expanded graphite-epoxy composite (EG-Epoxy) and expanded graphite-carbon nanofiberepoxy composite (EG-CNF-Epoxy) electrodes were investigated for electrochemical degradation of 4-chlorophenol (4-CP). Based on the investigated electrochemical techniques, e.g., cyclic voltammetry (CV) and chronoamperometry (CA), the operation conditions and the electrode suitable for electrochemical oxidation of 4-CP were selected. In addition, multiple pulsed amperometry (MPA) was applied for the in-situ electrochemical cleaning of the electrode surface to improve the electrode efficiency. The BDD electrode exhibited the best features related to the 4-CP electrochemical degradation efficiency.

“…The microorganisms were acclimated to grow on a test medium by using the Naugard Q ® compound as unique carbon source. The test medium was described by Aaronson [16] and the following alterations were made: 1.00 g of K 2 HPO 4 ; 0.20 g of MgSO 4 .7H 2 O; 0.10 g of NaCl; 0.10 g of CaCl 2 ; 0.02 g of FeCl 2 ; 1.00 g of (NH 4 ) 2 SO 4 ; 1000 mL of H 2 O; 0.60 g of Naugard Q ® compound; pH of 7.2 to 7.5.…”

The electrolytic treatment of a real industrial effl uent and simulated wastewater containing the 1,2-dihydro-2,2,4-trimethylquinoleyn compound (Naugard Q ® ) had been investigated in order to improve the wastewater biodegradability. The electrolysis was carried out in a batch electrolytic cell using 70TiO 2 /30RuO 2 electrodes (DSA ® anode). After electrochemical treatment, wastewaters were evaluated in terms of Naugard Q ® concentration, UV-visible spectrophotometry and biodegradation. Further analyses were conducted in simulated wastewater by gas chromatography and the biodegradation process was monitored using respirometric fl asks. Both real effl uent and simulated wastewater presented a decrease in Naugard Q ® concentration. The simulated wastewater electrolytic treatment provided concentration reduction of Naugard Q ® about 52.04% after 60 min, whereas real effl uent concentration was reduced by 62.60% after 40 minutes. Furthermore, UV-visible spectra and gas chromatograms presented signifi cant alterations in molecular structure of the compound. After 30 min electrolysis, an increase in simulated wastewater biodegradation was observed. In real effl uent, the biodegradation response was faster, as more CO 2 was produced in assays that underwent 10 and 25 minutes of electrolytic treatment. This result is probably related to modifi cations in Naugard Q ® molecular structure. It was concluded that the electrolytic treatment followed by bioremediation could be an alternate treatment to degrade this compound.
