Leaching behavior of sulfur concrete with fly ash used for removal of heavy metals from wastewater
Апстракт
When considering the materials that have become waste in a technological process, one way of their immobilization is for the production of certain new materials. The basic fact is to provide the environmentally acceptable level of the produced material. In this research fly ash from ’’Power Plant Nikola Tesla’’ Obrenovac was used as an sorbent for removal of heavy metals from flotation wastewater originating from artificial lake ’’Cerovo’’. After the sorption, fly ash was used as filler for the production of sulfur concrete. Sulfur concrete samples with standard dimensions were subjected to leaching tests by immersion in distilled water during the period of up to six months. Leaching is the process by which different contaminants are released from the solid phase into the water phase. The process itself is universal, as any material exposed to contact with water will leach components from its surface or its interior depending on the porosity of the material considered. Results of exami...ning leaching degree of heavy metals from the sulfur concrete samples with fly ash as filler showed that the leaching degree of all metals (copper, cadmium, zinc, iron, nickel) except manganese was negligible. It can be concluded that in the sulfur concrete samples with fly ash as filler, immobilization of heavy metals occurred.
