Abstract

he contamination of water resources by various organic pollutants,such as industrial dyes, has caused serious environmental problems.Some decontamination processes uses solid materials as adsorbents for the treatment of contaminated wastewater. These processes have suitable characteristics for implantation on an industrial scale, with high removal efficiency and low cost. The Advanced Oxidation Processes (AOPs), as heterogeneous photocatalysis, have also been used in the decontamination of water. The AOPs transform organic pollutants in easily degradable substances, typically inert or harmless. Multifunctional materials such as layered double hydroxides (LDHs) and their derivatives can be used for adsorptive and photocatalyticprocesses as well. Thus, this research project aims to study the multifunctionality of LDHs and their derivatives for removal and/or degradation of dyes. More specifically, the objectives of this project are: (i) synthesis and characterization of LDHs and their thermaldecomposition products, (ii) use of materials for the study of removal and/or degradation of textile dyes. The materials will be characterized by a set of techniques, including: XRPD, FTIR-ATR, SEM, XPS, TG, DSC and BET area. The degradation of dye will be measured by liquid chromatography coupled mass spectrometry (LC-MS) and UV-Vis spectrophotometry. (AU)
