activated carbon absorption News

  • ColorPlus – Absorption meter

    The two parameters UV-absorption and colour are important factors when monitoring the quality of potable water. The absorption at 254 nm wavelength reacts on humid substances and additionally shows the presence of other organic compounds such as oils, aromatics, solvents and other. By means like activated carbon filtration these substances need to be removed. Studies have shown that for most ...

  • Ocean Absorption of Carbon Dioxide More than Makes Up for Methane Emissions from Seafloor Methane Seeps

    The ocean waters near the surface of the Arctic Ocean absorbed 2,000 times more carbon dioxide from the atmosphere than the amount of methane that escaped into the atmosphere from the same waters, according to a study by the USGS Gas Hydrates Project and collaborators in Germany and Norway. The study was conducted near Norway’s Svalbard Islands, above several  ...

  • ASTM D6647 - 01(2011) standard test method for determination of acid soluble iron via atomic absorption

    In certain applications, such as acid purification, acidic food or chemical purification or decolorization, or other applications wherein iron may be leached out of the carbon, the use of acid-washed carbons will reduce or eliminate color pickup in the effluent or in the product. The acid soluble iron content is usually specified by the carbon supplier to prevent unacceptable levels of iron leach ...

  • A Tale of Two Cities' Black Carbon Measurement

    Advanced photoacoustic measurement of black carbon particles, using equipment available via UK-based Enviro Technology, has led to a better understanding of pollution in Los Angeles and Mexico City. PAX (Photoacoustic Extinctiometer) Black Carbon Monitors have been deployed to deliver a more accurate picture of daily black carbon trends in ...

  • Tree biodiversity increases release of carbon from soils

    Soils play an important role in the carbon cycle, containing more than two thirds of the total carbon held in terrestrial ecosystems. Concern about climate change and rising CO2 levels is driving research to understand carbon cycling through soils. New research suggests that in tropical regions greater tree diversity increases soil respiration (the release of carbon) rates, but also improves ...

  • Antarctic Ocean Losing Ability to Absorb Carbon Dioxide

    Norwich, UK - Recent climate change brought on by human activities has weakened one the Earth's natural defenses against global warming. Atmospheric carbon dioxide is not being absorbed by the Southern Ocean as quickly as it once was, an international research team has found. Scientists have observed the first evidence that the Southern Ocean’s ability to absorb the major greenhouse gas carbon ...

  • Forests can soak up a third of carbon emissions

    Looking after the world’s tropical forests would be worthwhile in its own right, for the sake of their human and animal inhabitants and their wider effects on the natural world. But researchers say it would also have a significant bonus. Properly cared for, the forests could cancel out between a quarter and a third of the planet’s carbon emissions. They argue that it is not just ...

  • Antarctica glacier retreat creates new carbon dioxide store

    Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. This remarkable colonisation is having a beneficial impact on climate change. As the blooms die back phytoplankton sinks to the sea-bed where it can store carbon for thousands or millions of years. ...

  • EPA issues final SNUR for certain multi-walled carbon nanotubes

    On May 6, 2011, the U.S. Environmental Protection Agency (EPA) promulgated a final significant new use rule (SNUR) under Section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the chemical substance identified generically as multi-walled carbon nanotubes (MWCNT), which was the subject of premanufacture notice (PMN) P-08-199. Under the final SNUR, persons intending to manufacture, import, ...

  • Mobile carbon capture technology removes 1000 kg CO2/day from Polish coal power plant

    Power plants are a major source of CO2 emissions and contributor to global warming. This study reports on a portable technology to remove CO2 from their combustion exhaust gases. Pilot testing on a coal burning plant in Poland captured thousands of kilograms of CO2 per day. This could be a viable future means of mitigating CO2 emissions from the power generation sector. The average temperatures ...
