Abstract:
Iranian researchers succeeded in the production of amperometric nanosensors to measure sulfite and nitrite by synthesizing cobalt nanoflowers and converting them into cobalt hexacyanoferrate.

Iran Using Cobalt Nanoflowers for Production of Nanosensors

Tehran, Iran | Posted on December 7th, 2012

Application in environmental and food industry measurement tools is among the advantages of the nanosensor.

Nanoflowers are compounds of elements, which have flower-like patterns at microscopic scale. However, they are classified in nanomaterials group because they have petal, pores, and nanometric parts. Due to their very high surface to volume ratio and appropriate physico-mechanical properties, such nanomaterials have received much attention from the scientists.

The research team succeeded in the production of cobalt hexacyanoferrate nanostructures by synthesizing cobalt nanoflowers and by carrying out anodic oxidation operation on the obtained nanoflowers.

"We started our research aiming to produce an amperometric sensor in order to measure sulfite and nitrite in the samples. Therefore, we firstly synthesized cobalt nanoflowers by using redox reactions in the presence of polyvinylpyrrolidone. The synthesized nanoflowers had petals and nanometric pores, which increased the quality of our operation," Dr. Helli, a member of the Scientific Board of Fars Science and Research Branch of Islamic Azad University and one of the researchers, explained about the research.

"Then, we produced amperometric nanosensor in order to measure sulfite and nitrite by the derivation of nanoflowers to cobalt hexacyanoferrate through the anodization of cyanoferrate solution and the preparation of modified carbon electrode paste."

Among the main characteristics of the nanosensors, mention can be made of simplicity, high sensitivity, low measurement limitations, appropriate selectivity and short response time.

Results of the research have been published on 30 August 2012 in Electrochimica Acta, vol. 77, pp. 204-301.
