Understanding molten salt chemistry is essential in ongoing research of the nuclear reactor (MSR). In this context, detailed understanding mechanisms underlying selective oxidation metal species, such as Cr, required to guide design effective corrosion mitigation strategies salts. An important starting point for mechanistic knowledge solvation structure and its role controlling speciation. work...

The article considers the processes of corrosion vehicle body influenced by road pollution components. It is noted that support frameworks, especially their bottom, are most susceptible to damage. This due presence in such bodies seams, gaps, as well hollow elements (spars, amplifiers, thresholds), which create favorable conditions for occurrence and development processes. A decisive role this ...

Corrosion of metals depends on the kind of metal and the prevailing conditions in the medium (temperature, pH, pressure, concentration, etc.) as well as the type of ions such as CO3 , NO − 3 , Cl − and NO2 present in the medium. It will be useful to briefly discuss the effects of some ions on metals. The ions mentioned above have different effects on metals. For example, CO3 is adsorbed on the ...

Information about the eruption of Mount Lawu in Central Java Province 1885 and Merapi D.I. Yogyakarta 2010 became a source for estimating presence magnetic minerals which underwent sedimentation process Bengawan Solo River from upstream (Wonogiri) - downstream (Bojonegoro). The results we get susceptibility distribution sediments reveal that sediment upper reaches has low frequency value around...

RATIONALE Characterising complex mixtures of organic compounds in polar fractions of heavy petroleum is challenging, but is important for pollution studies and for exploration and production geochemistry. Oil sands process-affected water (OSPW) stored in large tailings ponds by Canadian oil sands industries contains such mixtures. METHODS A polar OSPW fraction was obtained by silver ion solid...

In urbanized areas, the “freshwater salinization syndrome” (FSS), which pertains to long-term increases in concentrations of major ions and metals fresh surface waters, has been attributed road salt application. addition FSS, water composition changes as an influx sodium (Na + ) recharge may displace calcium (Ca 2+ ), magnesium (Mg potassium (K trace by reverse cation exchange. These changing i...

INTRODUCTION 1. Skin irritation refers to the production of reversible damage to the skin following the application of a test chemical for up to 4 hours [as defined by the United Nations (UN) Globally Harmonized System of Classification and Labelling of Chemicals (GHS)](1). This Test Guideline provides an in vitro procedure that may be used for the hazard identification of irritant chemicals (s...

BACKGROUND In 2003, residents of the District of Columbia (DC) experienced an abrupt rise in lead levels in drinking water, which followed a change in water-disinfection treatment in 2001 and which was attributed to consequent changes in water chemistry and corrosivity. OBJECTIVES To evaluate the public health implications of the exceedance, the DC Department of Health expanded the scope of i...
