Using the mineral component of building refuse in heavy metals sorption from their mixture
The sorption properties of the sand-breakstone mixture based on the mineral component of building refuse of the 0-10 mm fraction with respect to Pb2+, Zn2+, Cu2+, Ni2+, Cd2+ and Hg2+ ions were studied using atomic absorption spectroscopy. The mechanisms of accumulation of heavy metal ions on the sur...

| Summary: | The sorption properties of the sand-breakstone mixture based on the mineral component of building refuse of the 0-10 mm fraction with respect to Pb2+, Zn2+, Cu2+, Ni2+, Cd2+ and Hg2+ ions were studied using atomic absorption spectroscopy. The mechanisms of accumulation of heavy metal ions on the surface of the mixture particles are described. It was found that after washing the contaminated material distilled water, the residual concentration of metals in the filtrate does not exceed the established sanitary and hygienic standards. The practical value of the work lies in the possibility of applying the results in reclamation of technogenic formations or production of materials for the technical stage of reclamation using technogenic soils. |
