摘要： The invention relates to a method for biologically reducing the quantity of magnesium and/or iron in an asbestos waste product, characterised in that at least some of the iron and/or magnesium, which is contained inside said waste product or is on the surface thereof, is extracted by bringing said waste product into contact with siderophore-producing bacteria and/or bacterial siderophores until a modified waste product consisting of a solid phase and a liquid phase is produced.

摘要： The invention relates to a method for retaining cations within a calcium silicate hydrate CSH matrix, said cations being contained in water to be treated, wherein: a solid anhydrous mixture made up of at least slaked lime Ca(OH)
2 and nanometric silica (SiO
2 ) is used as a precursor of said calcium silicate hydrate CSH matrix; characterised in that: said anhydrous mixture is hydrated with said water to be treated containing the cations until synthesising said calcium silicate hydrate matrix, said matrix being provided in the form of a calcium silicate hydrate gel internalising and retaining said cations.
