PROCÉDÉ DE RÉTENTION DES CATIONS
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 (SiO2) 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.
