Description
Summary:Catalytic degradation cf tartrazine in the presence cf Oxone® activated by a catalyst constituted cf cobalt supported on a nanocomposite cf smectite with chitosan-derived carbon was investigated. The catalyst was synthesized using cobalt impregnation followed by carbonization at 773 K in an inert atmosphere. The synthesized catalyst was previously fully characterized using appropriate characterization methods, including XRPD, XPS, FT1R, HRTEM, and low-temperature N2-physisoi ption analysis. The catalytic experiments were peiformed by varying deferent experimental parameters (dye concentration, Oxone® concentration, temperature, and initial pH cf the reaction solution). The kinetic and thermodynamic parameters were estimated from the experimental results. The kinetics data showed the best fit with the pseudo-first-order kinetics model. The activation energy cf the investigated degradation process was calculated according to the Arrhenius equation. The catalyst showed excellent peiformance at low temperatures even at 298 K, and in the wide range cf pH values.
