As energy companies decide what to do with aging coal ash disposal facilities in North Carolina and across the nation, they may be overlooking a fundamental but potentially critical variable—oxygen.In...
An Evaluation on the Physical and Chemical Composition of Coal Combustion Ash and Its Co-Placement with Coal-Mine Waste Rock
Coal Combustion Ash Characteristic Co-Placement Sulfidic Waste Rock
2013/3/11
In the last few decades, the utilization of coal to generate electricity was rapidly increasing. Consequently, the production of coal combustion ash (CCA) as a by-product of coal utilization as primar...
Dissolution of Humic Substances from Highly Humic Volcanic Ash Soil as Affected by Anionic Surfactant, Electrolyte Concentration and pH
Surfactant Humic Substances Electrolyte Volcanic ash Aoil pH
2013/3/11
Dissolved humic substances separated from soils play an important role in the material cycle because they adsorb nutrients and contaminants and move with water. This study was conducted to investigate...
