An important issue in chlorine drinking water disinfection is the generation from natural organic matter (NOM) of disinfection by-products (DBPs), especially trihalomethanes (THMs). The THMs generation can be limited by reducing the levels of NOM prior to ...
The electrochemical oxidation of acidic solutions of phenol on a Ti/IrO2 anode has been investigated by cyclic voltammetry and bulk electrolysis in a single-compartment cell. In the potential region of oxygen evolution, anodic oxidation resulted in electro ...
Organohalide respiration (previously named as dehalorespiration) is a process during which microbes derive energy by the reductive dehalogenation of chlorinated organic pollutants and use them as terminal electron acceptors, hence helping in environmental ...
Several enrichment cultures were investigated in our laboratory for the bioremediation potential of tetrachloroethene (PCE). The underlying process, organohalide respiration (OHR), is based on bacterial anaerobic respiration in which the chlorinated compou ...
A taste and odour (T&O) episode in a Swiss town, where consumers complained about a musty odour in their drinking water, was investigated. The application of a combined organoleptic and instrumental method for T&O analysis allowed the identification of 2,4 ...
The relative basicities of aryllithiums bearing methoxy, chlorine, fluorine, trifluoromethyl and trifluoromethoxy substituents at the ortho, meta, and para positions have been assessed. To this end, two aryllithiums of comparable basicity were equilibrated ...
Enrichment cultures are investigated for the bioremediation potential of tetrachloroethene (PCE). This process is based on anaerobic respiration in which chlorinated compounds are used as electron acceptors (organohalide respiration, OHR). The key enzyme i ...
Five oxidants, ozone, chlorine dioxide, chlorine, permanganate, and ferrate were studied with regard to the formation of assimilable organic carbon (AOC) and oxalate in absence and presence of cyanobacteria in lake water matrices. Ozone and ferrate formed ...
Chemical oxidation processes have been widely applied to water treatment and may serve as a tool to minimize the release of micropollutants (e g pharmaceuticals and endocrine disruptors) from municipal wastewater effluents into the aquatic environment The ...
This study investigates focused electron beam induced etching for the removal of alumina particles on patterned extreme ultra violet (EUV) mask using nitrosyl chloride (NOCl) as assist gas. As potential contaminant, particles of aluminum oxide (alumina, Al ...
