This work presents some preliminary studies regarding natural zeolite, namely clinoptilolite (from volcanic zeolitic tuff) as selective adsorbent. This material was used to separate organic isomers of industrial interest (dichlorobenzenes, dinitrobenzenes, chloronitrobenzenes). The quality of the separations achieved were sufficiently encouraging as to promote further investigations of its potential as selective adsorbent both for bulk liquid separations and in analytical applications. These preliminary results showed that good chromatographic resolutions were obtained - RS,o,p-DCB=3.53; RS,o,p-DNB=3.09 and RS,o,p-CNB=4.25 and seem to be very promising in order to use this natural zeolite as selective adsorbent in different applications.
