Elimination organischer Spurenstoffe aus kommunalem Abwasser
… and nutrients, a great number of organic trace pollutants. These are industrial chemicals, pesticides, pharmaceuticals, natural and synthetic hormones, as well as ingredients of personal care products. Even in very low concentrations (ng/L to µg/L) some of these compounds can already have …

Solid Waste Degradation, Compaction and Water Holding Capacity
… account for attenuation of organics, metals and trace pollutants of adverse environmental consequences. Methodologies to improve the degradation rate and process are refuse shredding, nutrient addition, pH buffering, and temperature control along with moisture enhancement. Municipal Solid Waste …

Multiscale development of electrochemical separations: from molecular design of redox-moieties to interfacial characterization and process simulation
… sources, the environmental remediation of trace pollutants from water, and the improvement of downstream separations in chemical manufacturing, highlight the need for novel approaches with lower energy consumption, higher selectivity, and reduced chemical inputs. Electrochemistry can meet …

Laser Remote Sensing for Environmental Monitoring
… (DIAL) is able to analyze the distribution of trace pollutants in the atmosphere. Vertical measurements of two serious pollutants, atomic mercury and nitrogen monoxide, have been performed in the same Chinese city. Further, DIAL is also proved to be valid for remote gas analysis in …

Selective Ion Separations Using Shock Electrodialysis
… examples include the selective removal of trace pollutants, such as toxic heavy metal ions, from industrial effluents; the fractionation of chemically and physically similar elements, such as lanthanides for catalytic processes; the extreme deionization of wastewaters, such as radioactive …

Source identification of trichloroacetic acid with preparative capillary gas chromatography and accelerator mass spectrometry
… in a minute amount of a pure environmental trace chemical is accelerator mass spectrometry (AMS). In the present thesis an AMS equipped with a titanium-target gas source was used. Therefore, 1 microgram carbon in the form of carbon dioxide was sufficient for the measurement. To determine TCA …

Experimental and kinetic modelling of multicomponent gas/liquid ozone reactions in aqueous phase. Experimental investigation and Matlab modelling of the ozone mass transfer and multicomponent chemical reactions in a well agitatated semi-batch gas/liquid reactor.
Due to the ever increasing concerns about pollutants and contaminants found in water, new treatment technologies have been developed. Ozonation is one of such technologies. It has been widely applied in the treatment of pollutants in water and wastewater treatment processes. Ozone has many …
