Removal of Nі(II) and Cо(II) from aqueous solutions using crosslinked membranes
Clean water is the most essential element for the living organisms. Nowadays water resources are polluted by a large number of discharges from industrial and domestic sources, which make toxic effect on living organisms and ecosystems. The main industrial wastes are salts of heavy metals. Pollution of water by heavy metals is becoming a serious global problem. Membrane technology is considered to be one of the important wastewater treatment technologies. Adsorption and ion exchange methods are recognized as effective and economic methods to remove toxic metals from water solutions. Numerous examples of the synthesis of ion-adsorption and ion-exchange polymeric materials for the removal of heavy metal ions are presented in the scientific literature.
