Method of soil remediation

A method of treating material contaminated with organic pollutants, the method comprising providing material contaminated with organic pollutants, contacting the material with a matrix-generating agent capable of generating with the material a catalytically active alumino-silicate matrix, intimately mixing the material and matrix-generating agent, and maintaining the temperature of the resultant mixture at a level sufficiently high for a sufficient period to produce kerogenic compounds within said mixture.

A method of remediating soil contaminated with mixed organic and inorganic pollutants, the method comprising contacting the soil with a complexing agent selected from the group consisting of phosphoric acid, citric acid, trisodium phosphate and trisodium polyphosphate, and a matrix-generating agent comprising a cement, a silicon dioxide rich component and an organophilic clay, intimately mixing the complexing agent and the matrix-generating agent with the soil to produce a silicate matrix capable of binding with the pollutants, the matrix having an at least friable consistency.

A method of remediating soil contaminated with organic or inorganic pollutants, the method comprising contacting the soil with a complexing agent and a matrix-generating agent capable of authigenically generating within the soil a silicate matrix, the matrix having a plurality of catalytically active sites adapted for bonding of the pollutants, and intimately mixing the complexing agent and the matrix-generating agent with the contaminated soil to thereby authigenically generate said silicate matrix and bond said pollutants at said catalytically active sites in said matrix.
