Saturday, March 9, 2019 - 10:03

Researchers of Yadegar Emam IAU has created a system that removes copper ion from industrial waste through graphene sheets.

According to an ISCA report, the invention of removing copper ion through graphene sheets from industrial waste has been chosen as the top patent at the IAU 4th Festival on Nanotechnology 2019.

Nowadays heavy metals are the environmental priority pollutants and are becoming as the most serious environmental problems. In recent years removing those from diverse industrial effluents and metal cleaning have been studied.

Copper is one of the most valuable and prevalent metals used in the industry. There are many techniques to treat different types of industrial wastewater that are contaminated with heavy metals such as copper. The invention focuses on reviewing the most advanced wastewater treatment techniques.

With the rapid development of industries, water resource scarcity, population growth, pollution of surface and groundwater by discharging toxic wastewater and subsequent diseases may raise the necessity of reusing and treatment of wastewater.

The removing of toxic heavy metal ions from sewage, especially in industrial and mining waste effluents, has been widely studied in recent years. Heavy metals wastewaters are directly or indirectly discharged into the environment increasingly, especially in developing countries.

Unlike organic contaminants, heavy metals are not biodegradable and tend to accumulate in living organisms and many heavy metal ions are known to be toxic or carcinogenic. Toxic heavy metals of particular concern in treatment of industrial wastewaters include zinc, copper, mercury, lead and chromium.

The presence of heavy metal ions in the aquatic system causes serious health hazards to the human beings and also other living organisms. The wastewater from these industries frequently contain considerable amount of copper ions, which spread into the environment through soil and aquatic streams and finally gets accumulated along the food chain causing health hazards to the human beings.

The research has been carried out by Jamshid Najafpour, Sousan Samadi and Mohsen Jafarifard, faculty members of Yadegar Emam IAU which was selected as the top project at the IAU 4th Festival on Nanotechnology 2019.
