ABSTRACT Title of Document: CHARACTERIZATION OF TRACE METAL LEACHING FROM MARYLAND COAL FLY ASHES
Title of Document: CHARACTERIZATION OF TRACE METAL LEACHING FROM MARYLAND COAL FLY ASHES Enes Ozkok, Master of Science, 2011 Directed By: Associate Professor Ahmet Aydilek, Department of Civil and Environmental Engineering Three coal fly ashes with different acid-base characteristics and their mixtures with an embankment soil were analyzed for arsenic, copper, and chromium leaching as function ...
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 کاملOn the Radioactivity of Fly Ashes from Coal Power Plants
The radioactivity of Greek lignites and their ashes was studied. It was found that the radionuclides in them belong to the uranium series. Fly ashes are relatively rich in radioactivity. Concentrations up to 7 , 1 0 _ 5 g / g and 12 pCi/g were measured for 238U and 226Ra, respectively. The associated hazards from radioactivity escaping from stacks of thermopower plants or when fly ashes are use...
