Production of Nanosorbent in Iran to Remove Aromatic Pollutants

Iranian researchers from Shahid Bahonar University of Kerman succeeded in the production of a sorbent with comparable advantages over the commercial sorbents in the extraction and removal of pollutants.

The sorbent is produced through a simple and cost-effective method and no disturbing bi-product is produced during the process.

In this study, a polymeric nanocomposite layer was synthesized and used for the extraction and measurement of a type of multi-cyclic aromatic hydrocarbons taken from samples of polluted water.

The nanocomposite can be produced easily and in addition to having a long lifetime, it has also appropriate stability at high temperatures, to the extent that the tests showed that it can be used about 80 times at 280°C without any changes in sorption properties.

Multi-walled carbon nanotube/poly ortho aminophenol nanocomposite was used in the production of the sorbent. The coating has been deposited on the surface of a wire made of stainless steel as the electrode to measure and adsorb cancerous pollutions in various environments. Real samples have been used in this research to study the validity of the method and its application in the separation and measurement of pollutants, including multi-cyclic aromatic hydrocarbons. Wastewater of coal washing unit, agricultural water near the factory, river water and drinking water of the city were also tested.

Results showed that the produced nanocomposite is able to effectively separate and remove the pollutants.
