The present work describes, for the first time, use of a new and strong complexing agent, ethylenediamine-N,N'-disuccinic acid (EDDS) in homogeneous Fenton process. effect H(2)O(2) concentration, Fe(III)-EDDS pH value, oxygen concentration on degradation bisphenol A (BPA) used as model pollutant, was investigated. Surprisingly, performance BPA oxidation an EDDS-driven reaction found to be much higher at near neutral or basic than acidic pH. Inhibition probe studies were conducted ascertain...
This work constitutes the first large report on aerobic cultivable microorganisms present in cloud water. Seven cloud-event samples were collected at Puy de Dôme summit, and cultivation was performed leading to isolation of 71 bacterial, 42 fungal 15 yeast strains. Most fungi isolated Cladosporium or Trametes affiliation, yeasts Cryptococcus affiliation. Bacteria, identified basis their 16S rRNA gene sequence, found belong Actinobacteria, Firmicutes, Proteobacteria (Alpha, Beta Gamma...
The goal of this paper was to develop a modified photo-Fenton treatment able degrade micro pollutants in municipal wastewater plant (MWTP) effluents at neutral pH with minimal iron and H2O2 concentrations. Complexation Fe by ethylenediamine-N,N′-disuccinic acid (EDDS) leads stabilization solubilization natural pH. Photo-Fenton experiments were performed pilot compound parabolic collector (CPC) solar plant. Samples treated solid phase extraction (SPE) analyzed HPLC-Qtrap-MS. rapid degradation...
Abstract. Long-term monitoring of the chemical composition clouds (73 cloud events representing 199 individual samples) sampled at puy de Dôme (pdD) station (France) was performed between 2001 and 2011. Physicochemical parameters, as well concentrations major organic inorganic constituents, were measured analyzed by multicomponent statistical analysis. Along with corresponding back-trajectory plots, this allowed for distinguishing four different categories air masses reaching summit pdD:...
In this study, the activation of persulfate induced by Fe(III)-ethylenediamine-N,N′-disuccinic acid (EDDS) under dark and irradiation conditions reactivity generated sulfate radical (SO4•–) a wide range experimental were investigated means kinetic analyses modeling. The Fe(III)-EDDS was found to be efficient across pH value (3–7), whereas second order rate constant SO4•– with 4-tert-butylphenol (4tBP) kSO4•–,4tBP = (4.21 ± 0.22) × 109 M–1 s–1 unchanged between 2.5 8.5. Experimental...
The photoinduced degradation of an alkylphenol ethoxylate (APE) (Igepal CA 520) by Fe(III) in aqueous solution has been investigated. A complete characterization the commercial product showed presence a mixture compounds with various ethoxy and alkyl chain lengths. photodegradation study was carried out major fraction ethoxymers having length 8 carbon atoms n units E (C8PhEn). We have demonstrated that sensitized this occurs efficiently both at 365 nm under sunlight. rate depends on...
Abstract. The chemical composition of cloud water was investigated during the winter-spring months 2001 and 2002 at Puy de Dôme station (1465 m above sea level, 45°46′22′′ N, 2°57′43′′ E) in an effort to characterize clouds continental free troposphere. Cloud droplets were sampled with single-stage collectors (cut-off diameter approximately 7 µm) analyzed for inorganic organic ions, as well total dissolved carbon. Results show a very large variability solute concentration droplets, ranging...
