Synthesis of novel nanocomposite sorption materials based on zirconium (IV) oxide and activated carbon to remove heavy metals from waterproperties


Particular attention among methods of water purification deserves sorption method using a sorbent is activated carbon, due to its cheapness. However, its sorption capacity for many metal ions, unfortunately, is not high enough. In order to increase these last modified sorbents. As modifiers can be used as metal oxides, which are also effective sorbents. Among them it is worth noting ZrO2. It is an effective sorbent to ions of different nature, including heavy metals. However, its use in nano-sized state as a modifier can increase the sorption capacity due to high specific surface area and exchange capacity, which further increases during the transition from the crystalline to the amorphous phase.Thus, innovation involves the creation of new sorption nanocomposite materials based on zirconium (IV) oxide and activated carbon to be used for the selective removal of heavy metal ions from aqueous solutions.
