The Effect of the Nature of Inorganic Ions on Hydrocarbon Flotation

Abstract

The liquid hydrocarbons hexadecane and pseudocumene (1,2,4-trimethyl-benzene) were removed from their O/W-type emulsions by flotation. The effect of different inorganic salts (NaCl, Na₂SO₄, Na₃PO₄) on the removal efficiency was investigated. It was shown that the inorganic salt effect on flotation efficiency is connected with their influence on the double-layer thickness and on the adsorption of surface-active ions.
