摘要:
The invention refers to a process to separate silicates and alkaline earth metal carbonates implementing at least one hydrophobically modified polyalkyleneimine, wherein: i) the polyalkyleneimine is hydrophobically modified by replacement of all or part of the hydrogens of their primary and/or secondary amino groups by functional group R, where R comprises a linear or branched or cyclic alkyl and/or aryl group and contains 1 to 32 carbon atoms; ii) prior to modification, the polyalkyleneimine has at least 3 alkyleneimine repeat units and a molecular weight of between 140 and 100 000 g/mol; iii) modification of the polyalkyleneimine results in an increase in the atomic C amount, relative to the unmodified polyalkyleneimine, of between 1 and 80%.

The invention additionally refers to a silicate-containing product and an alkaline earth metal carbonate-containing product obtained by the process of the invention, and to their uses.
摘要:
The present disclosure relates to a method for cleaning contaminated soil including a process which grinds contaminated soil to separate contaminants present on the surface of the contaminated soil from the soil, and a process which injects air into a mixture of water and contaminated soil having undergone the surface grinding process to generate air bubbles and removes only the generated air bubbles to remove the contaminants included in the air bubbles.
