Polarographic Oxidation of Phenolic Compounds

Preparation and characteristic of cobalt phthalocyanine modified carbon paste electrode for bisphenol A detection

“…doi:10.1016/j.jelechem.2008.11.004 reaction and enhancing the sensitivity and selectivity of the detection method [18]. Electrochemical methods have been used successfully in the detection of some phenolic compounds since most of phenols can be oxidized at readily accessible potentials [19,20]. It is well known that cobalt phthalocyanine complexes can effectively catalyze the electrooxidation of organic compounds for the function of redox mediators.…”

Investigation of the Electrochemical Characteristics of Organic Compounds

“…These two compounds actually have been obtained from phenol by electrolytic oxidation and by oxidation with peroxysulfuric acid. Because these dihydroxy compounds are oxidized even more easily than phenol itself, the oxidation generally proceeds further and yields other products (9). The relative difficulty of oxidizing phenol is apparent from the markedly lower anode potential of this compound as compared with the potentials of the di-and tri-hydroxybenzene compounds.…”

“…The curve has a slope of --0.058 in close agreement with the theoretical value of --0.0591. The half-wave potential of hydroquinone also has been found to decrease linearly with increasing pH in the range of pH 1 to 8 (9).…”

Decontamination Systems Information and Reseach Program

“…Only minor discrepancies can be found for formation of CH 2 Cl 2 and destruction of CH 2 Cl between the complex and reduced kinetic models. Figure 6.2 shows the destruction of CH 2 Cl. The reduced model takes a slightly small time for destruction of CH 2 Cl, but the agreement is still good.…”
