Sorbent and Photocatalytic Potentials of Local Clays for the Removal of Organic Xenobiotic: Case of Crystal Violet

Natural materials are widely used in the field of environmental remediation and appreciated for their surface physical chemical properties. Clay constitutes a typical example. In this work, we report evaluation sorbent photocatalytic potentials local clay two irrigated rice waters degradation crystal violet. The structural, textural compositional properties were investigated by Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD) Fluorescence (XRF) analysis. analysis results showed that these composed mainly quartz kaolinite. efficiency adsorbents (Y. L. Clay) to eliminate violet dye from aqueous medium was examined at different initial concentrations, pH, contact time, adsorbent dose possible interference inorganic salts fertilizers. Kinetic studies adsorption process well described pseudo-second order model equilibrium modelling fitted adequately Freundlich model. maximum amount uptake capacity achieved pH 2.0 18.40 (mg·g−1) 20.40 (mg·g−1), respectively, Y. Clay. potential raw samples do not show activities during 30 min exposure UV light. On other hand, is manifested when loaded with titanium dioxide (TiO2). Clays coupled TiO2 under light an improvement 15%. synergistic effects between high activity strong clays can be one promising technique situ contaminated soaked field.
