Chemical Fixation of Heavy Metal-Contaminated Soils
The U.S. Environmental Protection Agency (EPA) has been working toward the establishment of treatment standards for contaminated soils. The Office of Emergency and Remedial Response is in the process of developing and carrying out a plan to address the data needs for establishing the Pest Demonstrated Available Technologies (BDAT) for Superfund soils. The BDAT program is divided into phases. Ph...
متن کاملUtilization of nSiO2, fly ash, and nSiO 2/fly ash composite for the remediation of triphenyltin (TPT) from contaminated seawater.
The removal of triphenyltin chloride from contaminated simulated seawater with adsorption method was discussed. The adsorbents used are fly ash, nSiO2, and nSiO2/fly ash composite. The results showed that the adsorption of the adsorbents increases with increase in the adsorbent dose, contact time, pH, stirring speed, initial TPT concentration, and decreased with increase in temperature. The ads...
متن کاملSuppressing Heavy Metal Leaching through Ball Milling of Fly Ash
Ball milling is investigated as a method of reducing the leaching concentration (often termed stablilization) of heavy metals in municipal solid waste incineration (MSWI) fly ash. Three heavy metals (Cu, Cr, Pb) loose much of their solubility in leachate by treating fly ash in a planetary ball mill, in which collisions between balls and fly ash drive various physical processes, as well as chemi...
متن کاملAbundance and diversity of Archaea in heavy-metal-contaminated soils.
The impact of heavy-metal contamination on archaean communities was studied in soils amended with sewage sludge contaminated with heavy metals to varying extents. Fluorescent in situ hybridization showed a decrease in the percentage of Archaea from 1.3% +/- 0.3% of 4', 6-diamidino-2-phenylindole-stained cells in untreated soil to below the detection limit in soils amended with heavy metals. A c...
متن کاملLeaching Behavior of Petroleum Contaminated Soils Stabilized with High Carbon Content Fly Ash
Utilization of recycled materials as a substitute for natural soils in engineering applications such as highway construction is an emerging application area. A research study was conducted to investigate the stabilization of petroleumcontaminated soils (PCSs) using another recycled material, high carbon content fly ash (HCCFA), and evaluate the feasibility of using the final product in highway ...
