The present study has been dedicated on the removal process of heavy metal ions from electrolyte solutions by using methods of electroflotation and subsequent filtration in a multi-component system with the presence of various surfactants of different nature. The research was conducted in a five-component system comprising ions of iron (II), nickel (II), copper (II), plumbum (II), and zinc (II) (the total concentration of metal ions is 200 mg/l). The research was conducted in a highly concentrated electrolyte solu...

Liquid industrial wastes from the production of calcium chloride represent CaCl2 solutions with different impurities, most notably ferric ion (III). This article analyses sparingly soluble iron (III) compounds removal from CaCl2 via electroflotation. We determined the optimal pH value for sparingly soluble iron compounds removal from CaCl2 via electroflotation followed by filtration. The iron compounds removal in a most complete manner was found at ?? 6 - 7. Polyelectrolyte (flocculating agents) and surfactants we...
