Compositions in accordance with the principles of the present invention comprise a compressed mixture of fibrous organic materials and multi-valent metals used to remove organic chemical contaminants. The compositions are made into a pre-shaped, compressed form used to form a permeable reactive barrier for decontamination of soils, sediments, sludges, and waters containing environmental pollutants. The compressed mixture, comprising the fibrous organic particles and one or more multivalent metallic particles, is formed into reactive pellets, granules, and other pre-shaped structures for use in constructing a reactive barrier, typically for use in a contaminated environment or in an industrial process. By way of example, the pre-shaped structure may be used to construct a reactive barrier to remove halogenated organic chemical contaminants, nitroaromatic organic contaminants, or certain inorganic contaminants from various terrestrial and aquatic based ecosystems.

Les compositions selon les principes de la présente invention comprennent un mélange comprimé de matières organiques fibreuses et de métaux multivalents utilisée pour éliminer des contaminants chimiques organiques. Les compositions sont préfaçonnées et comprimées afin de former une barrière réactive perméable pour décontaminer des sols, sédiments, boues et eaux contenant des substances polluantes de l'environnement. Le mélange comprimé contenant les particules organiques fibreuses et une ou plusieurs particules métalliques multivalentes est façonné pour former des agglomérés, des granules et autres structures préfaçonnées utilisées pour construire une barrière réactive, typiquement utilisée dans un environnement contaminé ou dans un processus industriel. Par exemple, la structure préfaçonnée peut être utilisée pour construire une barrière réactive pour éliminer des contaminants chimiques organiques halogénés, des contaminants organiques nitro-aromatiques ou certains contaminants inorganiques dans différents écosystèmes terrestres et aquatiques.
