The coupling use of the heterogeneous Fenton-like process (zero-valent iron (Fe0)/H2O2) and weak magnetic field (MWF) for bisphenol A (BPA) abatement was systematically investigated in this study. Though both Fe0/H2O2 WMF-Fe0/H2O2 processes are sensitive to pH, WMF remarkably enhanced BPA removal under pH range 3.0–6.0 by 0.5–9.5 times. characterization Fe0 confirmed role promoting corrosion Fe...

In this work, the usefulness of Conductive Diamond Electrochemical Oxidation (CDEO) to degrade caffeine in real urban wastewater matrixes was assessed. The oxidation of actual wastewater intensified with caffeine (from 1 to 100 mg L(-1)) was studied, paying particular attention to the influence of the initial load of caffeine and the differences observed during the treatment of caffeine in synt...

The absence of significant detectable signatures organic molecules in the atmosphere and on surface Mars is a major unsolved puzzle. One possible explanation that perchlorate-rich Martian soils, activated by solar ultraviolet (UV) radiation, create an environment favorable for rapid oxidation organics such as alkanes (including methane or CH4). In this paper, we measured product formation rates...

Inspired by the reactivity of (per)chlorate reducing molybdoenzymes and encouraged lack molybdenum-containing functional models thereof, two molybdenum(VI) complexes type [MoO2L2] (L = pyrimidine-2-thiolate or 6-methylpyridine-2-thiolate) were found to be active homogeneous catalysts for reduction ClO4– ClO3– in CH2Cl2 using PPh3 as sacrificial oxygen acceptor. The subsequent stepwise Cl– is fa...

Introduction: the recent discovery of perchlorates (ClO4) by Phoenix triggered a high interest for this rare ion on the surface of the Earth [1]. Indeeed perchlorate solutions have very low eutectic favoring potential liquid water on the surface [2]. The mechanisms by which such a highly oxidized ion formed remain largely unknown. Two major pathways are possible: atmospheric oxidation of aeroso...

Thin films of ammonium perchlorate (NH4ClO4) were exposed to energetic electrons at 5.5 K to explore the radiolytic decomposition mechanisms. The effects of radiolysis were monitored on line and in situ via Fourier transform infrared spectroscopy (FTIR) in the condensed phase along with electron impact ionization quadrupole mass spectrometry (EI-QMS) and single-photon photoionization reflectron...
