Chemical Fixation of Trace Elements in Coal Fly Ash
More than two-thirds of the coal combustion by-products (CCBs) produced in the United States are disposed of in dry landfills or in wet ash lagoons. Most of the older ash disposal sites are unlined and many are unmonitored. The US EPA is currently developing national standards for monitoring groundwater at coal combustion byproduct disposal facility (CCBDF) sites in the US. Development of effec...
متن کاملMajor-to-ultratrace elements in bone-marrow fluid as determined by ICP-AES and ICP-MS.
The major-to-ultratrace elements in human bone-marrow fluid were determined by ICP-AES (inductively coupled plasma atomic emission spectrometry), and ICP-MS (inductively coupled plasma mass spectrometry). The bone-marrow fluid sample was centrifuged prior to acid digestion to exclude the bone piece from bone marrow, and then digested with nitric acid. As a result, 20 elements could be determine...

متن کاملDistribution of trace elements in coal and coal fly ash and their recovery with mineral processing practices: A review
Today coal is among the most important energy sources. In order to meet the world's energy demands, low-calorie lignite with a high ash content is generally used in the large capacity coal-fired thermal power plants. As a result of coal firing, wastes such as fly ash, slag, and flue gas are also produced. Subsequently, toxic trace elements within coal are transferred to wastes such as slag, fl...
متن کاملSimultaneous determination of trace elements in minute samples by electrothermal-vaporization/low-pressure helium-ICP-MS.
Electrothermal vaporization with two filaments was studied for low-pressure helium-ICP-MS. A 10-microl volume of sample was dried and vaporized, and then introduced to the ICP. With this technique, four elements were simultaneously determined with the acceptable precisions (RSD ca. 10%). The detection limit based on 3sigma of background signals approached the fractional ppb range. The proposed ...
