Abstract

Cadmium(II) and Pb(II) ions replace the sodium(I) ion in commercial molecular sieve deolite. These exchanged derivatives have been interacted with adsorbates like CO2 and NH3 and the new exchanged and adsorbed derivatives characterized by their TG and IR spectral data. It is concluded that deolite can be effectively employed for removal of hazardous Cd(II) and Pb(II) ions as well as the gaseous adsorbates.

Zusammenfassung

Kadmium(II)- und Pb(II)-Ionen ersetzen das Natrium(I)-Ion im handels-üblichen Molekularsieb Deolite. Diese ionengetauschten Derivative traten mit Adsorbaten wie CO2 und NH3 in Wechselwirkung und die neuen ausgetauschten und adsorbierten Derivative wurden durch ihre TG- und IR-Daten charakterisiert. Man zog den Schluß, daß Deolite effektiv zur Entfernung von gefährlichen Cd(II)- und Pb(II)-Ionen als auch der gasförmigen Adsorbate eingesetzt werden kann.
