Absolute quantification of water in microporous solids with (1)H MAS NMR and standard addition

Tijdschriftbijdrage - Tijdschriftartikel

Zeolites are microporous materials driving industrial scale adsorption, ion exchange and catalytic processes. Their water content dramatically impacts their properties, but its quantification with Karl Fisher titration or thermal gravimetric analysis is problematic. Combining standard addition of water with 1H MAS NMR detection, absolute quantification of water in microporous materials becomes possible. The method was demonstrated on 5 different, commercially available zeolites.
