The research studied the effects of solubility, disperse features (Z average diameter dav, and charge (?-potential) of the particles of heavy-metal slightly soluble compounds exemplified by aluminum (III), zinc (II) and plumbum (II) hydrates related to efficiency of their removal from aqueous solutions in the composition of 2- and 3-component systems by means of electroflotation and filtration within a wide pH-range (5 ? 12). The metals in question demonstrate various pH-values of hydrates formation and solution. ...

The research studied the effects of solubility, disperse features (Z-average diameter dav, and charge (?-potential) of the particles of non ferrous-metal slightly soluble compounds of different natures exemplified by hydrates, carbonates, phosphates and sulfides of cuprum(II) and nickel(II) related to efficiency of their extraction from aqueous solutions through electroflotation. The research showed that minimum solubility of the dispersed-phase? particles of cuprum(II) and nickel (II) cannot be used to predict th...
