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.
