Abstract:

FLAMIR project will develop new biodegradable polymeric materials to be used for flocculation/coagulation processes in the treatment of surface and waste waters. The synthesis of such eco-materials will be performed by electron beam induced grafting of synthetic monomers onto biopolymers as an alternative to the classic synthesis chemical methods of polyelectrolytes. The project follows also the improvement of polyelectrolytes with silver nanoparticles which confer unique and considerably changed bio-physico-chemical properties. In this view, the synthesis of biodegradable organic polyelectrolytes with superior properties than synthetic ones using a modern and rapid method which meets the environmental protection needs is considered. Moreover, electron beam treatment accelerates the copolymerization process and therefore considerably reduces the copolymer preparation time and the amount of energy required for grafting reaction compared with the classical method. It is also able to increase significantly the conversion of monomers reducing the percentage of residual monomer to near zero and thus their toxicity. The experimental tasks will mainly aim: the development, implementation, optimization and demonstration of functionality and efficiency of the proposed grafting experimental model; the synthesis of a wide range of biopolymer-based polyelectrolytes and their accurate physico-chemical, structural and functional investigation; the demonstration of functionality and efficiency of polyelectrolytes by water/wastewater treatment tests at laboratory and pilot plant level, and the environmental impact by biodegradability, aquatic ecotoxicity and sludge inhibition tests. The project implementation through an interdisciplinary consortium of 4 partners consisting in research institutes, academic and SME research organization will deliver a new generation of green products to our society and promote an ecological and economic feasible, cheap method to obtain them.

Abstract:

Most of the research in the field of nanoscience is dedicated to the development of synthesis routes to nanoparticles and nanostructures. There are many novel properties and applications of nanoparticles demonstrated: from catalysis, environmental remediation, biomedical to information displays, and electronics.

Among the various photocatalysts, titania occupies a very important place. Recently, titanium dioxide has been extensively used for the decomposition of environmental pollutants as a possible alternative to conventional water treatment technologies.

The concept of the present project is to use sol-gel un-doped and doped-TiO2 (with transitional metals) nanopowders photocatalysts as friendly materials for the environment in the advanced degradation of xenobiotic compounds from waste water resulted from industrial activities.

The novelty and the importance of this project consist in the art to build the TiO2-based nanomaterials and to establish their photocatalytic performances in a proper equipment with solar energy for the water depollution.

The project has a distinct complexity degree through its modality of tackling which refer to the synthesis of the doped-photocatalysts, photocatalytic processes and fluctuating context regarding the wastewaters with different proveniences.

Considering the competence of the partners which form the consortium in different but complementary research fields (such as: the synthesis and characterization of nanopowders, the depollution of the water, and the kinetic evaluation of the degradation procedures) as well as the special results obtained in the previous projects together with the target of the central and local environment authorities regarding the diminution of the pollution with toxic, xenobiotic compounds, it can be appreciated that the present project proposal is viable and successfully conceived.
