Abstract:

The dispersion of urea onto the surface of clinoptilolite was studied. The data of XRD and IR clearly showed that urea can disperse onto the surface of clinoptilolite spontaneously and it has a threshold of 0.12g/g. The possible interaction between dispersion urea and the surface of clinoptilolite was discussed. This research has promising futural application.

Key words: Clinoptilolite, Urea, Spontaneous dispersion
