Abstract
Our study is focused on a new family of microporous solids with controlled microporosity, namely pillared clays. These materials are studied on a large scale for varied application and especially for different polluants retention. This paper presents the manufacturing of nanomaterials able to retain radioactive cations from polluted waters. The experiments were performed with the same starting material: bentonite from Valea Chioarului (Romania) deposits.
