AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Electrochemistry can bring important contributions to current applications, such as organic synthesis or wastewater treatment. In an environmental context, electrochemical processes are interesting substitutes to the conventional wastewater treatment techn ...
This study focuses on the mineralization of 5-amino-6-methyl-2-benzimidazolone (AMBI), an important precursor in the industrial production of dyes, through an integrated Fe(III) photoassisted–biological system without addition of other electron acceptor th ...
A promising elimination treatment of non-biodegradable org. pollutants is the direct electro-oxidn. The electrochem. elimination of polyacrylates by using B-doped diamond as anodic material was proposed. The complete elimination of org. contaminants was ob ...
The catalytic activity of IrO2 catalyst used as an electrode on a YSZ solid electrolyte cell for the gas phase combustion of ethylene can be increased by electrochem. pre-treatment. Thus, the polarization of the IrO2 electrode for 90 min at 300 mA, relativ ...
We studied the electrochemical oxidation, on Pt anodes, of industrial wastewaters containing 5-amino-6-methyl-2-benzimidazolone (AMBI). Electrolysis of this non-biodegradable effluent produces simultaneous oxidation of AMBI and chloride ions. Highly oxidat ...
The electrochem. behavior of PbO2 and synthetic B-doped diamond thin film electrodes (BDDs) was studied in acid media contg. 4-chlorophenol (4-CP) by bulk electrolysis under different exptl. conditions. To quantify the electrochem. activity of a given elec ...
The electrochem. oxidn. of 3-methylpyridine (3-MP) at synthetic boron-doped diamond (BDD) thin film electrode was studied in acid media by cyclic voltammetry and bulk electrolysis. The results showed that in the potential region of water stability there ca ...
5-amino-6-methyl-2-benzimidazolone (AMBI), used in the manufacture of dyes, was characterised as a biorecalcitrant compound by means of different biodegradability tests. In order to enhance the biodegradability of this important pollutant, the application ...
A combined chemical-biological treatment of industrial wastewater using ozonation as the first step of a Sequencing Batch Biofilm Reactor (SBBR) process, in which 3-methylpyridine (3MEP) was degraded as a model industrial pollutant, has been developed. The ...
The electrochem. oxidn. of phenol in the presence of NaCl for wastewater treatment was studied at Ti/SnO2 and Ti/IrO2 anodes. The presence of NaCl catalyzes the anodic oxidn. of phenol only at Ti/IrO2 anodes due to the participation of electrogenerated ClO ...
