Bicarbonate enhances the transformation of phenol upon irradiation of hematite, and phenol nitration upon irradiation of both nitrate and nitrite. Hematite under irradiation is able to oxidise the carbonate ion to the CO3-. radical, which in turn oxidises phenol to the phenoxyl radical faster compared to the direct photo-oxidation of phenol by hematite. The formation of CO3-. from hematite and ...

As in many other microorganisms, the growth rate of C. tropicalis is affected by phenol. Besides, when the yeast is aerobically cultivated in a medium containing phenol, using a bubble column, the yeast cell flotation phenomenon occurs, which makes the continuous operation of this type of reactor difficult. Therefore, a system of phenol degradation, which recycles the biomass separated by flota...

Phenol was extracted from sebacic acid wastewater (SAWW) using liquid-liquid extraction in batch as well as serial modes by applying different solvent: SAWW (1:250 5:250, v/v). Alcohols (1-hexanol, 1-heptanol, and 1-octanol), castor oil and Aliquat-336® were used for phenol extraction. In a typical extraction experiment involving shaking and allowing for phase separation, phenol (75-96%) can be...

Pseudomonas sp. strain CF600 metabolizes phenol and some of its methylated derivatives via a plasmid-encoded phenol hydroxylase and meta-cleavage pathway. The genes encoding the multicomponent phenol hydroxylase of this strain are located within a 5.5-kb SacI-NruI fragment. We report the nucleotide sequence and the polypeptide products of this 5.5-kb region. A combination of deletion analysis, ...

Adsorption of 1-Butanol, Phenol, and P-nitrophenol on activated carbon havebeen studied. The results were used to testifying the validity of different modelsbased on thermodynamic principles: Freundlich, Langmuir and Henry isotherms.The maximum capacity of adsorbent for three compounds was determined, Theconstants of equilibrium were determined by Freundlich isotherm and virialisotherm expressi...

phenol is an environmental pollutant present in industrial wastewaters such as refineries, coal processing and petrochemicals products. in this study three phenol degrading bacteria from arak petrochemical complex effluent were isolated which consume phenol. molecular analysis was used to identify bacteria and isolated bacteria were identified as rhodococcus pyridinivorans (ns1), advenella faec...

background and objectives: dairy companies always try to increase the quantity and quality of milk production. according to the positive impact of different plants on milk production of cattle, this study was carried out to standardize a galactogogue herbal mixture based on its total phenol and flavonol contents and antioxidant activity.  methods: a mixture of galega officinalis l. and nigella ...

The aim of this study is to evaluate the biodegradation performance of phenol in a fixed biofilm developed in sand soil media. The parameters which had been studied and may influence the biodegradation were: a) the grain size of sand, b) the rate of flow, and c) the initial phenol loading. Laboratory scale of two columns with inner diameter of 5 cm was used. The first column was packed with fin...

The objective of this preliminary study was to partially replace phenol in the synthesis of phenol-formaldehyde resin with feather protein. Feather protein–based resins, which contained one part feather protein and two parts phenol, were formulated under the conditions of two feather protein hydrolysis methods (with and without presence of phenol during hydrolysis), two formaldehyde/phenol mola...
