Adsorption of metal ions on natural and substituted celluloses

Abstract

Corpora non agunt nisi fluida sive soluta" – substances do not react unless in a liquid or dissolved state. This ancient rule is no longer universally valid as attested "by the new phenomena "being found every day; column chromatography by solid powders may be one of the most noteworthy exceptions. In talking about column chromatography, immediately one thinks of Ion Exchange Resins. In fact, for the few past decades, analytical and inorganic chemists have concentrated their interest in the applications and theoretical interpretations of the behaviors of ion-exchange resins. Resins indeed deserve this, for so many fantastic achievements in chromatography have been made since the organic chemists had succeeded in their synthesis. But at the same time, the powders of celluloses have also been used widely and successfully for separations of biological and organic substances; this finally awakened inorganic and analytical chemists to realize that they might have ignored something which may be equally interesting and promising.
