Mobilization of heavy metal, metalloid and actinide elements, used for reducing pollution in soil, sediment, deposits and water-purification slurry, involves treating substrate with non-oxidizing gas in presence of water and reducing agent

摘要

Improving the mobility and/or mobilization of heavy metal, metalloid and actinide elements from substrates comprises treating the substrates with a non-oxidizing gas phase in the presence of moisture and reducing agent.
