Ion flotation is a separation technique used in the field of environmental remediation and wastewater treatment. It involves the removal of target ions from aqueous solutions by adsorbing them onto the surface of air bubbles, which are then carried to the surface and removed. This method is particularly useful for the removal of heavy metal ions, radioactive ions, and organic pollutants from water sources. Ion flotation is a cost-effective and environmentally friendly method compared to other traditional separation techniques. Research in this field focuses on improving the efficiency and effectiveness of ion flotation for various applications in water treatment.
