Abstract

Laboratories studies were conducted for the removal of Cu(II) from aqueous solution using adsorbing colloid flotation with Fe(OH)₃. The effects of pH, surfactant (sodium lauryl sulfate), and foreign ions (NO₃⁻, SO₄²⁻) on the removal efficiency of Cu(II) were investigated. Sodium lauryl sulfate was efficient as a surfactant for the removal of Cu(II) and the optimum pH was found at 8.0. Foreign anions highly inhibited Cu(II) removal efficiency. This limitation of foam flotation on Cu(II) removal at high ionic strength may overcome by the aid of activators. The applicability of activators to improve Cu(II) removal efficiency of foam flotation was verified experimentally. The adsorption and separation mechanisms for the removal of Cu(II) are discussed. The role of activators on Cu(II) removal is also discussed.
