  • Biosorption study in a mining wastewater reservoir

    An in situ sorption was conducted to assess the behaviour of cations in a mining wastewater reservoir. Sorption experiments on test materials showed that biomass mainly bound uranium, copper, lead, zinc, and nickel, whereas goethite bound arsenic and chromium. Clay minerals bound both barium and rare earth elements. The lacustrine sediments mainly contained iron oxy-hydroxides. Desorption ...

  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • Moisture in Oils: The Three-Headed Beast

    Abstract Moisture contamination in in-service lube oils is perhaps one of the most destructive forms of engine corrosion second only to particle contamination.  Water contamination in oil can be categorized into three forms of water; Free, emulsified, and dissolved.  All forms of water have direct consequences to the oil and gears of the engine, but indirect consequences as ...

  • Determination of effective cation exchange capacity and exchange acidity by a one-step BaCl2 method

    Routine laboratory procedures measure effective cation exchange capacity (ECEC) and exchangeable acidity (EA) using separate extractants. This study assessed the suitability of a one-step BaCl2 extraction for the analysis of both ECEC and EA on organic and mineral soils by comparing results to those of a multi-step BaCl2 extraction already in use by Europe's International Cooperative Programme ...

  • In-Situ® Optical RDO® Methods for Dissolved Oxygen Measurements Outperform Traditional Methods

    ABSTRACT Three methods are generally used to measure dissolved oxygen (DO) in surface waters: Winkler titration, membrane-covered electrochemical sensors (polarographic or galvanic cell), and luminescent-based sensors. Optical (luminescent) technology for measuring DO levels in water has quickly become a well-accepted method due to many advantages over membrane-based sensors, and its close ...
