O mém projektu

The water treatment is a constant concern for human being along the years, with the purpose of maintaining a sustainable development of water quality, environment, and public health. The declination of physical and chemical water quality due to human influences is often gradual, and subtle adaptations of aquatic ecosystems to these changes are not always detected until a dramatic shift into the ecosystem condition occurs. Endocrine Disruption Compounds, EDCs are involved in this these consequences and may interfere with the normal endocrine function of both wildlife and humans. EDCs include steroid hormones and various industrial chemicals comprising care products/cosmetics such as phthalates, parabens, chlorinated compounds as well as polychlorinated biphenyls or alkylphenols may also affect the reproduction in humans, wildlife or aquatic organism by disrupting their endocrine functions, e.g. hormones secreted by human ovaries, testes, thyroid or other organs. Heterogeneous photocatalysis process is effective and promising for many reactions, such as carbon dioxide reduction, photocatalytic water splitting, and organic transformations. The organic substances that are presented as pollutants into the water (EDCs), can be achieved efficiently by photocatalytic degradation which not only is categorized as an advance oxidative Process (AOP) developed for water purification but also as a green technology featured unique advantages of operation. TiO2 is considered as a superior semiconductor due to its high photocatalytic activity that leads to a complete oxidation of the organic pollutants including EDCs via hydroxyl HO. or band hole h+ during the AOP. The aim and original contribution of the project is to achieve a maximum efficiency in the transformation of the reactants during the process of purification of service water from organic pollutants (EDCs) by producing a highly stable TiO2 photocatalytic Reactor system immobilized in a reactive organosilicon binder and developing a new method of quantification of EDCs.
