Wastewater treatment from toxic metals by flotoextraction


Photoextraction of Ni(II) and Cu(II) ions has been investigated at pH 3-9.3 using potassium oleate and triethanolamine as collecting agents and octane, decane, and decanol as an organic phase. The maximum extraction rate of the specified ions amounts to 72 and 52% respectively. All possible structures of sublates were analyzed using data of IR-spectroscopy.
