Electroflotation removal of the dispersed phase of sparingly water-soluble non-ferrous and heavy metals from aqueous media. Effect of the composition of the aqueous medium on the removal efficiency

摘要

The article describes the effect of the composition of the aqueous medium on the surface characteristics (zeta-potential, solubility, particle size, and dispersity) of the disperse phase of sparingly water-soluble non-ferrous and heavy metal compounds, as well as on their removal by the electroflotation method. The electroflotation efficiency can be improved by varying the surface characteristics of the dispersed phase by varying the pH and redox potential of the medium, as well as using different reagents and certain types of water-soluble polyelectrolytes of different functionalities under conditions optimal for their work.
