Wastewaters polluted with high concentration of dyes are produced by various industries.
Therefore, it is important to perform treatment of the dye-contaminated waters before their
discharge into recipients in order to protect the environment. Sulfate radical-based advanced
oxidation processes that involve use ofactivated Oxone® can be used for degradation of dyes.
In this work,nanocomposite catalysts constituted ofCo supported on smectite with chitosanderived
carbon were used for activation of Oxone. Catalysts were synthetizedusingan
impregnation-carbonization procedure and denoted as Co/cCh-S-T (T stands for applied
carbonization temperature). The carbonization was performed in the temperature range from
400°C to 700°C in the flow of N2 providing inert atmosphere. The synthesized catalysts were
fully characterized using XRPD, XPS, FTIR, HR-TEM, and low-temperature N2-
physisorption analysis, and evaluated in the Oxone® induced oxidative degradation of food
dye tartrazine. ...The best performing catalyst was investigated in detail regarding catalytic
degradation of tartrazine with respect to degradation time and different experimental
parameters (dye concentration, Oxone® concentration, temperature, and initial pH of the
reaction solution). The kinetic and thermodynamic parameters were calculated from the
experimental results.The selected catalyst showed excellent performance in the Oxone®
initiated tartrazine degradationat low temperatures (even at 25°C) and in the wide range of pH
values.
