Phenol is an organic pollutant found in various types of industrial wastewater. Due to its bactericidal properties, it is difficult to eliminate it by classic treatment methods. In this work, the degradation of this compound by Fenton reaction at mild temperature and pressure conditions is studied. An experimental design was applied in order to quantify the influence of operating parameters on ...

Simultaneous determination of multicomponents of phenol, resorcinol and catechol with a chemometric technique a PCranking artificial neural network (PCranking-ANN) algorithm is reported in this study. Based on the data correlation coefficient method, 3 representative PCs are selected from the scores of original UV spectral data (35 PCs) as the original input patterns for ANN to build a neural n...

Perovskite-like oxides SrCo1-xTixO3-δ (SCTx, x = 0.1, 0.2, 0.4, 0.6) were used as heterogeneous catalysts to activate peroxymonosulfate (PMS) for phenol degradation under a wide pH range, exhibiting more rapid phenol oxidation than Co3O4 and TiO2. The SCT0.4/PMS system produced a high activity at increased initial pH, achieving optimized performance at pH ≥ 7 in terms of total organic carbon re...

Treating a synthetic wastewater containing phenol as the sole substrate at 26°C, an upflow anaerobic sludge blanket reactor was able to remove over 98% of phenol up to 1,260 mg/l in wastewater with 12 h of hydraulic retention time, corresponding to 6.0 g-COD/(l·day). Results showed that benzoate was the key intermediate of phenol degradation. Conversion of benzoate to methane was suppressed by ...

The electrochemical oxidation of iodide in the presence of phenol and o-cresol was investigated at a glassy carbon electrode in buffered media by cyclic voltammetry, linear sweep voltammetry and controlled–potential coulometry. The experimental results indicate that the phenol and o-cresol convert to their derivatives after participating in a halogenation coupled reaction (quasi-catalytic react...

An assay system was developed for the enumeration of genetically engineered microorganisms expressing a deregulated 2,4-dichlorophenoxyacetate (TFD) monooxygenase, which converts phenoxyacetate (PAA) to phenol. In PAA-amended cultures of Pseudomonas aeruginosa PAO1C(pRO103) and Pseudomonas putida PPO301(pRO103), strains which express a deregulated TFD monooxygenase, phenol production was propor...

Five different protocols, viz. Andleeb et al. (2012), Shrivastava et al. (2012), Phenol chloroform DNA extraction method, Roboscreen Kit method and Phenol chloroform triton method, were tested for DNA extraction from skin samples of Leopard (Panthera pardus) preserved in formalin over a period of two to five months. Among these procedures, the Phenol chloroform triton method was proved to be th...

Carbon-coated TiO2 catalysts were found to have high photocatalytic activity for photodecomposition of methylene blue in water, higher than TiO2 without carbon coating [1]. However, these catalysts used for phenol decomposition showed lower activity than TiO2 without carbon coating. Also lower adsorption capacity of phenol on carbon-coated TiO2 catalysts was noted by comparison with adsorption ...

Phenol biodegradation in batch systems using Cupriavidus taiwanesis 187 has been experimentally studied. To determine the various parameters of a kinetic model, combinations of rearranged equations have been evaluated using inverse polynomial techniques for parameter estimation. The correlations between lag phase and phase concentration suggest that considering phenol inhibition in kinetic anal...

Effect of Ascotbate on Covalent Binding of Benzene and Phenol Metabohtes to Isolated Tissue Preparations. SMART, R. C. and ZANNONI, V. G. (1985). Toxicol. Appl. Pharmacol. 77, 334-343. [‘4C]Phenol and [‘4C]benzene are metabolized in the presence of NADPH and hepatic microsomes isolated from phenobarbitalor benzene-pretreated or untreated guinea pigs to intermediates capable of covalently bindin...
