Modelling the change in the oxidation coefficient during the aerobic degradation of phenol by acclimated activated sludge
(Water Research Commission, 2014-01)
In this work the aerobic degradation of phenol by acclimated activated sludge was studied. Results demonstrate that while the phenol removal rate by acclimated activated sludge follows the Monod model, the oxygen uptake ...
Analytical methodology optimization to estimate the content of non-flavonoid phenolic compounds in Argentine propolis extracts
(Taylor & Francis, 2014-02-07)
Context: Traditionally, the content of total phenolics (flavonoid phenolics (FP) and nonflavonoid phenolics (NFP)) and flavonoids (flavone/flavonol and flavonone/dihydroflavonol)in propolis has been determined by different ...
Phenolic compounds from nuts: Extraction, chemical profiles, and bioactivity
(American Chemical Society, 2020-01)
Nuts contain a vast array of phenolic compounds having important biological properties. They include substances allocated into the five major groups named phenolic acids, flavonoids, tannins, phenolic lignans, and stilbene ...
Method for phenol recovery from “alperujo”: numerical optimization and predictive model
(Springer, 2019-08)
“Alperujos” of Arbequina olives harvested in 2010 and 2011 and of Nevadillo olives in 2012 were evaluated in order to reduce their pollutant load by recovering the phenols with antioxidant properties. First, three successive ...
Magnetite supported hematin as a biomimetic of horseradish peroxidase phenol removal by polymerization
(Taylor & Francis Ltd, 2004-01)
Phenol removal using HRP and hematin as biomimetic of HRP is presented at selected conditions at room temperature. The best results are obtained with treatment in two steps, with double addition of HRP or hematin and a ...
Tobacco hairy root's peroxidases are rhythmically controlled by phenol exposure
(Elsevier Science Inc., 2021-09)
Plants like almost all living organisms, have developed a biological clock or circadian clock (CC) capable of synchronizing and adjusting various metabolic and physiological processes at certain times of the day and in a ...
Application of the film-pore diffusion model to the sorption of phenol onto activated carbons prepared from peanut shells
(SAGE Publications, 2008-11-01)
In this work, the film-pore diffusion model was applied to the adsorption of phenol onto peanut shell activated carbon in a batch stirred vessel. This two-resistance model was applied to predict the phenol concentration ...
Antioxidant activity and quantification of phenols, flavonoids and total tannins of Cinnamomum triplinerve (Lauraceae)
(Universidade Federal de Santa Maria, 2019)
Catalyst systemas for the oxidation of phenol in water
(Planta Piloto de Ingeniería Química, 2004-12)
The oxidation of phenol solutions (5 g/L) has been studied in a semibatch autoclave reactor. Activity screening experiments were performed over two commercial catalysts: CuO+ZnO (Topsoe) and CuO+NiO (Engelhard), and CuO/Al2O3 ...
The influence of environmental variations on the phenolic compound profiles and antioxidant activity of two medicinal Patagonian valerians (Valeriana carnosa Sm. and V. clarionifolia Phil.)
(AIMS Press, 2021-01)
Valeriana carnosa and V. clarionifolia stand out as principal elements in the indigenous pharmacopeias of Patagonia; however, their phytochemical characterization is unknown. This study constitutes the starting point of a ...
