    Mercury monitoring for mercury flux measurement

    The Tekran 2537 has been used in numerous published studies to measure the deposition or evasion of mercury from natural or contaminated surfaces (i.e. flux measurements). It is anticipated that many mercury flux measurements will be needed in the future to assess the impact of climate change on mercury cycling in the environment. There are two basic ways to do mercury flux measurements. First, the dynamic flux chamber method utilizes a custom enclosure, with controlled air flow, to measure the...

    Mercury determination in natural, surface, sea, drinking, bottled, mineral, and waste water by cvaas

    Introduction

    Mercury determination in natural, drinking, and waste waters is one of the most popular analyses used for environment pollution and sanitary control. Background concentrations of mercury in natural water are within several ng/l. Maximum national permissible levels for mercury in water lie in the range of 0.16–6 µg/l. For example, the following limits for mercury in drinking water are set, µg/l:
    0.5 – Japan, Russia;
    1 – Argentina,...

    Analytical instruments for atomic spectroscopy

    Besides Mass Spectrometry, a further variety of analysis techniques are categorized as atomic spectroscopy. Analysis techniques which use inductively coupled plasma (ICP), such as ICP-OES and ICP-MS, are among these. With increasing environmental awareness backed by regulations, an increasingly important use of atomic spectroscopy techniques is in mercury analysis. Achieving a high mass flow control performance, e.g. high repeatability or an excellent turn-down ratio, is a prerequisite to achieve a high...

  • Agitation and mixing solutions for flue gas desulfurization

    FGD (Flue Gas Desulfurization) involves the treatment of flue gas from coal fired power plants.  The main goal is to remove sulfur, particulates, and other chemicals such as mercury from the flue gas prior to environmental release.  Governmental regulations by the EPA put limits on the amount of impurities which can be released into the air.   The use of mixers to clean and scrub the flue gas is utilized to help power companies meet permitted limits on the release of controlled substances.
