Partially-puri®ed extracellular laccase of Coriolus versicolor transformed chlorophenols in the following order: 2,4,6trichlorophenol > 2,6-dichlorophenol > 2,4-dichlorophenol, 2-chlorophenol > 2,3-dichlorophenol. On the other hand, 3and 4chlorophenols, 2,5-, 3,4and 3,5-dichlorophenols, 2,4,5-trichlorophenol and pentachlorophenol were recalcitrant to the laccase. Sinapinic acid, a naturally-occ...
In this work, the photoelectrocatalytic (PEC) degradation of 2,5-dichlorophenol can be used for its removal from aqueous solution. To study this activity, a TiO2 thin film modified titanium sheet (TiO2/Ti) was fabricated by anodizing Ti plates using a two electrode system under the constant bias voltage of 20 V for 20 min in a solution of 0.2% (v/v) HF followed by calcinat...
The authors regret that in our article the data for 2,4-dichlorophenol (CAS 120-83-2) need to be corrected. In Table 1 the corrected BAF of 2,4-dichlorophenol is 38 L/kgwet weight, the corrected MEFM1 (2,4-dichlorophenol-sulfate) is 1935 L/kgwet weight, and the corrected MEFM2 is 129 L/kgwet weight. In Table 2 the corrected model parameters (with 95% confidence intervals) for 2,4-dichlorophenol...
BACKGROUND Exposure to certain phenols is ubiquitous because of their use in many consumer and personal care products. However, predictors of exposure have not been well characterized in most populations. OBJECTIVES We sought to identify predictors of exposure and to assess the reproducibility of phenol concentrations across serial spot urine samples among Chinese adults. METHODS We measure...
Background and purpose: 2,4 dichlorophenol is one of the most important components of organochlorine. High resistance against degradation, creating odor and taste in water, high toxicity and being carcinogen have made this pollutant a great concern. Current study batch was done to investigate the adsorption of 2,4 dichlorophenol onto Magnetic Graphene Oxide Particles (MGO NPs). Materials and...
The novel nanocomposite membranes were successfully prepared by the incorporation of different concentrations (5, 10, and 15 wt%) of montmorillonite (MMT) as a nanoadditive into a blend of chitosan/polystyrene (CS/PS) at a ratio of 3:1 on the basis of solution-casting method and they were subsequently used for the separation of phenol, p-chlorophenol, and 2,4-dichlorophenol from water through p...
Anaerobic (microaerophilic) acetylene reduction by Azolla caroliniana Willd. was dependent on light and saturated at approximately 450 foot candles. Maximum rates of acetylene reduction were 60 nmoles/mg chlorophyll minute. However, rates of 25 to 30 nmoles/mg chlorophyll minute were more common.The growth of Azolla for 35 days with nitrate or urea as a nitrogen source decreased the rate of ace...
Photoelectrocatalytic (PEC) water treatment is a promising technology for organic pollution abatement. Much of the prior research focused on material discovery and optimization. However, challenges exist in scaling-up PEC processes are associated with designing reactors effective light irradiation electrode surfaces and, simultaneously, efficient configurations. We design demonstrate key reacto...
It has been suggested that monoterpenes emitted within the soil profile, either by roots or by decaying biomass, may enhance the biodegradation of organic pollutants. The aim of this study was to evaluate the effect of biogenic volatile organic compounds (VOCs) on the catabolism of 2,4-dichlorophenol in soils. Soils were collected from areas surrounding monoterpene (woodland) and nonmonoterpene...
The formation and structure of inclusion complexes of αand β-cyclodextrins with 2-chlorophenol (2CP), 3-chlorophenol (3CP), 4-chlorophenol (4CP), 2,4-dichlorophenol (24DCP), 2,6-dichlorophenol (26DCP) and 3,4-dichlorophenol (34DCP) have been studied by UV-VIS and 1H NMR spectroscopy. Both cyclodextrins were found to form 1 : 1 inclusion complexes. Binding constants estimated from titration stud...
