Perspective Wastewater Treatment from Cu 2+ Ions in the Mining Industry

摘要

The synthesis of new cation-exchanger based on local raw materials for the extraction of copper from copper-containing solution investigated. A review of the literature regarding the problem of ion exchange method and the use of mine wastewater treatment process is presented. Sorption selectivity of Cu~(2+)ions by cation exchanger in the H-and Na-forms from dilute solutions was studied in the target concentration range 90 mg/dm~(3)and 5,49 g/ dm~(3). The full dynamic exchange capacity calculated. The cation exchanger analyzed with consideration for IR spectroscopic, chemical analysis, and scanning electron microscopic data. Quantum-chemical calculations performed that synthesized cation-exchanger stable complexes with Cu~(2+)ions. Obtained cation exchanger due to excellent behavior recommended removing copper ions from wastewater in the mine industry.
