Abstract:
Iranian researchers at University of Tabriz produced an electrode made of carbon nanotubes which is capable of highly removing colorants from industrial wastewaters.

Carbon Nanotube Electrode Removes Colorants from Industrial Wastewaters

Iran | Posted on January 17th, 2010

"First, we fabricated PTFE carbon nanotube and PTEF graphite electrodes to be used as cathodes. Then, we measured hydrogen peroxide produced by the two mentioned electrodes through electrolysis. After that, we removed C.I. Basic Yellow 2 pollutant from contaminated waters by the fabricated electrodes," Mahmoud Zarei, one of the researchers said to the news service of INIC.

"The results show that hydrogen peroxide produced by carbon nanotube electrode is about three times and thirty times greater than that of carbon electrode and graphite electrode respectively. SEM and AFM images taken from electrodes surfaces imply an increase in contact area of carbon nanotube electrode and more production of hydrogen peroxide," he said, elaborating on the results of the research.

Zarei said that C.I. Basic Yellow 2 removal efficiency by carbon nanotube electrode through proxy coagulation process is about 96% in the first ten minutes of electrolysis.

"During this period, C.I. Basic Yellow 2 removal efficiency by carbon electrode through electric coagulation, electro-Fenton, and coagulation proxy were 21%, 53%, and 62% respectively. This reveals the high capability of carbon nanotube in colorants removal", he added.

The privilege of the present study over the similar ones is an increase in peroxide hydrogen production meaning higher process performance leading to electrolysis time shortening and process costs reductions.

About Iran Nanotechnology Initiative Council (INIC)
Iran has recognized the significance of nanotechnology like other pioneering countries and started its activities in line with development of the technology. In this regard and as first step, a Study Committee for Nanotechnology in Iran began its activities in 2001 and finally Iran Nanotechnology Initiative Council (INIC) was established in the country in 2003.

The INIC is tasked with determining the general policies for the development of nanotechnology in the country and pursuing the case with implementation of the policies.
Iranís success in achieving a proper place among 15 countries which are advanced in nanotechnology and making attempt to promote the position in a bid to develop Iranís economy are the main missions of the INIC.

Iran Nanotechnology Initiative Council is seeking to pave the ground for activity of the private sector and production of wealth within the society through adopting outlook, providing facilities, creating market and removing the existing problems.
