| 摘要 |
Various solid/porous substrates, including soil, clay, sand, stone; articles of manufacture, such as transformers and other hardware items, and liquid substrates, such as dielectric fluids, and the like, contaminated with potentially toxic organic compounds are decontaminated and recycled for further use by treating with solvated electrons either at the situs of the toxic spill or by batch treatment in a reactor. The process can utilize solvated electrons prepared chemically or electrochemically. Advantageously, substances such as water believed to compete with the selectivity between solvated electrons and the toxic substance or interfere with the stability of solvated electrons need not be removed from contaminated substrates. Other embodiments of the invention include methods of treating porous substrates with chemicals for solubilizing the toxic material for more efficient elevation of contaminates especially from porous surfaces. The methods of the invention are also especially useful in the destruction of bulk quantities of CFCs known to be harmful to the earth's ozone layer.
