Originální abstrakt

The proposed work describes new perspectives for recycling of a salty industrial wastewater to microstructured iron oxides with capturing potential for minor carbon- and metallic contaminations. Byproducts generated by electrochemical treatment of a rubber wastewater with sacrificial steel anode were separated, dried, desalinated, and thermally processed at 800 and 1100 °Cin a nitrogen atmosphere to investigate the effects of chemically bound oxygen on iron oxide formation. The obtained powder products were different phases of iron oxides, such as hematite, maghemite, magnetite; depending on the annealing temperature. All of the phases are interesting from a recycling point of view, the microstructure, elementary composition and crystallinity of the solid products before and after thermal treatment were investigated via SEM-EDX and PXRD techniques.
