Fe-impregnation was implemented in order to produce heterogeneous Fenton catalysts for Reactive Blue 4 dye degradation. Materials characterization demonstrated a rise in the specific surface area due to decomposition of WSH constituents during carbonization (to obtain BC) and thermal activation (to obtain Fe-WSH and Fe-BC), thus producing catalysts with high mesoporosity and hematite as the active site for Fenton reaction. Among the investigated materials, Fe‑WSH showed the greatest ability for <sup>•</sup>OH production in acidic medium. Next, the hetero­geneous Fenton process was optimized by using response surface methodology, which resulted in selection of the following reaction conditions: 3 mM H<sub>2</sub>O<sub>2</sub>, 100 mg Fe-WSH, reaction time of 180 min, at a constant pH 3, RB4 concentration of 50 mg dm<sup>-3</sup> and at room temperature. The achieved dye removal and mineralization were 85.7 and 66.8 %, respec­ti­vely, while the catalyst showed high stability and the reaction intermediates formed during the oxidation process had a low inhibitory effect on <em>Vibrio fischeri</em> bacteria.</p>}, number={5}, journal={HEMIJSKA INDUSTRIJA (Chemical Industry)}, author={Kulić Mandić, Aleksandra and Bečelić Tomin, Milena and Pucar Milidrag, Gordana and Rašeta, Milena and Kerkez, Đurđa}, year={2021}, month={Oct.}, pages={307–320} }
