Industrial wastewaters contain metal cations, which are very dangerous for the life and health of living organisms and always have a destructive and irreparable effect on the environment. Heavy metals mean lead, mercury, zinc, nickel, chromium, cadmium, and so on. The presence of heavy metals in water sources in a concentration higher than the standard value causes very dangerous complications.
There are various techniques to reduce the concentration of heavy metals, which can be mentioned as chemical co-precipitation, reverse osmosis phenomenon, evaporation, ion exchange, and absorption. Using the absorption technique is one of the effective and practical techniques. The development of new products that are effective absorbent, have the least harmful effect on the environment, are inexpensive, and can be used to remove and reduce the concentration of heavy metals in industrial wastewaters is one of the most important topics in materials science and engineering. The purpose of expressing this challenge is to use ceramic absorbents as an absorbent material to remove heavy metals from industrial wastewater.
