Özet
This study presents the improved method of smectite type clays pillaring, using aluminum salts. To achieve this goal, natural clay with a percentage of more than 95% montmorillonite was used. In order to analyze the pillaring process, a thermal procedure was used (thermal programmed desorption). The results of the pillaring process show that a controlled distance between the foliar band structures as long as 18 center dot 10(-10) m can be obtained. The clays modified by pillaring can be used as molecular sieves in microfiltration processes or as agents in residual water chemical depolluting processes. They also have zeolite properties which make them reusable.
