Abstract
These studies are based on the investigation carried out on the cation-exchange and adsorption bahavior of a natrolite-type natural zeolite collected as a geological specimen as a powdered sample. Cd-natrolite was prepared with saturated aqueous cadmiun(II) sulfate solution with continuous shaking at 60° for maximum interaction. A portion of this exchanged derivative was then heated over a Nicker burner for several days in a nickel crucible. Both the original and the preheated Cd I I -zeolite samples were also interacted with gaseous H 2 S and liquor ammonia to study their sorption capacity and preheating affects. All the derivatives and the original zeolite before and after heating were analyzed by XRD, FTIR and thermal methods.
