Abstract:
Researchers from University of Mohaghegh Ardebili in Iran and University of Bath obtained the technology to produce a nanosensor in order to measure environmental pollutants called dihydroxybenzene.

Effective Elimination of Industrial Pollutants with New Nanosensors

Tehran, Iran | Posted on November 1st, 2012

The achievement was made by studying the voltammetry of dihydroxybenzene isomers on the surface of glass carbon electrode modified with carbon nanoparticle - chitosan composite film with high surface area.

In addition to its reasonable price, the presented electrode is able to adsorb huge amounts of impurities in dihydroxybenzene.

Catechol (1,2-dihydroxybenzene), resorcinol (1,3-dihydroxybenzene), and hydroquinone (1,4-dihydroxybenzene) are the three isomers of dihydroxybenzene, which are used in cosmetics, pesticides, scent and flavor essences, drugs, antioxidants and chemicals for photography and paint.

"Carbon structures, including glass carbon, carbon nanotube, and its other forms are important in electro-analysis. Carbon nanomaterials play an important role in electrochemical processes due to their high surface area and high active bonds. Electrodes modified with carbon nanoparticles have advantages such as catalysis of electrochemical reactions by increasing the rate of ion exchange and increasing the mass transfer due to high specific area. These properties of carbon nanoparticles are used in order to modify sensor properties," Dr. Mandana Amiri, a member of the Scientific Board of Mohaghegh Ardebili University, stated about the research.

In this research, real samples of water such as water of a local river and the wastewater of a rubber factory were analyzed in the presence of the electrode. Results showed 96-108% recycling at various concentrations.

Results of the research have been published on 20 February 2012 in Sensors and Actuators B: Chemical, vol. 162, issue 1, pp. 194-200.
