    Fenton like Method for Contaminated Groundwater
    (2017) A. Russo; Silvia E. Jacobo
    Advanced oxidation processes (AOPs) have been widely proposed to treat wastes, particularly less concentrated effluents. Fenton-like is a useful technique to remove different organic compounds. A supported catalyst prevents iron release during all the process. In earlier works we explored the porous structure of a modified natural clinoptilolite loaded with iron as a supported catalyst (NZ -A-Fe). This paper presents novel results for BTX (Benzene, Toluene and Xylene) removal from aqueous solution considering that adsorption and oxidation processes are taking place simultaneously. The experiment was achieved by fluxing an aqueous solution of BTX 10 mM and hydrogen peroxide using the same reservoir. After 870 min, C/C reaches near 10% for each pollutant corresponding to 122 bed volumes. The system removed 225 mg BTX in the present conditions (45 mg/gNZ-A-Fe). Hydrophobic Fe-zeolites can therefore be regarded as promising materials for the removal of BTX from water, since they allow the combination of efficient adsorption and oxidative degradation of BTX by H2O2 at neutral pH.
