  2. Perfluorocyclohexane - Wikipedia

    en.wikipedia.org/wiki/Perfluorocyclohexane

    Perfluorocyclohexane is chemically inert and thermally stable. It is a relatively non-toxic, clear, waxy solid, which has a high vapor pressure and therefore sublimes readily at room temperature. [citation needed] The molecule predominantly exists in its chair conformation, in which it possesses D 3d molecular symmetry.

  3. Fluorocarbon - Wikipedia

    en.wikipedia.org/wiki/Fluorocarbon

    Perfluoroalkanes are very stable because of the strength of the carbon–fluorine bond, one of the strongest in organic chemistry. [4] Its strength is a result of the electronegativity of fluorine imparting partial ionic character through partial charges on the carbon and fluorine atoms, which shorten and strengthen the bond (compared to carbon-hydrogen bonds) through favorable covalent ...

    en.wikipedia.org/wiki/Perfluorohexane

    Perfluorohexane (C 6 F 14), or tetradecafluorohexane, is a fluorocarbon.It is a derivative of hexane in which all the hydrogen atoms are replaced by fluorine atoms. It is used in one formulation of the electronic cooling liquid/insulator Fluorinert for low-temperature applications due to its low boiling point of 56 °C and freezing point of −90 °C.

    en.wikipedia.org/wiki/Environmental_chemistry

    Environmental chemists draw on a range of concepts from chemistry and various environmental sciences to assist in their study of what is happening to a chemical species in the environment. Important general concepts from chemistry include understanding chemical reactions and equations , solutions , units , sampling , and analytical techniques .

    Natural gas (mostly methane) is an even more potent greenhouse gas when it escapes into the atmosphere prior to being burned. Since the industrial age began circa 1750–1850 with growing wood and coal use, the atmospheric concentration of carbon dioxide and methane have increased about 50% and 150%, respectively, above their relatively stable ...

  7. Perfluorinated compound - Wikipedia

    en.wikipedia.org/wiki/Perfluorinated_compound

    The environmental concerns for perflurocompounds are similar to chlorofluorocarbons and other halogenated compounds used as refrigerants and fire suppression materials. The history of use, environmental impact, and recommendations for use are included in the Kyoto Protocol.

  8. Phytoremediation - Wikipedia

    en.wikipedia.org/wiki/Phytoremediation

    Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]

    Some research shows the concentration of such substances is even higher in water leaving the plant than water entering the plant. Many factors including environmental pH, seasonal variation, and biological properties affect the ability of an STP to remove PPCPs. [2] A 2013 study of a drinking water treatment plant found that of 30 PPCPs ...
