Project summary
During the last decade a great interest has been accorded to the synthesis and applications of a conceptually new class of (bio)organic-inorganic hybrid materials. The classical approach to combine the properties of different materials has led to the development of composite materials or lends, where two different phases with complementary physical properties are combined.
Although such materials are macroscopically homogeneous, their properties reflect the nature of the chemical building blocks of which they are composed. The blending of organic and inorganic components and the synergism of their properties in one material is particular useful and allows the development of materials with totally new properties. The synthesis of the (bio) organic-inorganic hybrid materials leads to multifunction materials and the properties control from an atomic scale to a nanometric one.
That is why one of this project objective is the development of new technologies for the hybrid materials synthesis either by grafting the organic component into a mesoporous inorganic substrate or by the sol-gel procedure, starting from inorganic precursors such as metallic alcoxides or organically functionalized alcoxides, the inorganic ions complexing agents being an organic or a biochelating compound.
That kind of hybrid materials can be used with success either for electrochemical sensors with a great sensibility and selectivity, or for inorganics removal and retention from polluted aqueous media. For this reason one of the objectives of this project is to manufacture miniaturized electrochemical sensors that allow fast in-situ evaluation of inorganic ion concentrations.
Another objective of this project is the development of a new procedure for the selective removal and retention of inorganics from polluted aqueous media. Mesoporous silica or alumosilica functionalized with chelatant ligands or containing specific biochelatants for different inorganic ions will be used as active materials. In order to develop a new technology for selective removal and retention of different inorganics, both sensor and inorganic retention unit will be incorporated into an integrated system for the continuous monitoring of inorganic concentration level and diminution of their values in aqueous media.asamblati
