Iranian Researchers Develop Novel, Low-Cost Method to Measure Hydrazine

Iran | Posted on November 16th, 2010

The recent reports on severe hydrazine poisoning indicate that swallowing about 20-50 ml of hydrazine can prove to be fatal. It has been proved that hydrazine causes cancer on laboratory animals. However, there is not enough evidence to prove such claim about humans. Therefore, the measurement of hydrazine is an important issue, in which the Tabrizi researchers have taken important steps.

"Electrochemical methods are the cheapest, simplest, and they are also the most exact methods in order to measure hydrazine," Mirqassem Hosseini, a lecturer at University of Tabriz, told the news service of Iran Nanotechnology Initiative Council.

"The major problem for measuring hydrazine with solid electrodes is its relatively high tendency for oxidation. Metals such as gold, platinum, and silver are suitable for anodic oxidation of hydrazine, but they are not cost-effective in industry due to the economic limitations," he added.

Mirqassem believes that the solution to this problem is the use of "modifiers for the electrode surface".

"To this end, titanium has been used as the sub-layer in this research."

Noting that titanium is an active metal that oxidizes quickly at room temperature and a non-homogeneous and sticky layer of titanium oxide is formed on its surface, he said, "Therefore, the first stage is to remove that sub-layer, which is possible through various methods."

"After the removal of the sub-layer off the surface of titanium, we formed a coating of polyaniline through an electro-polymerization process. Then we formed a coating of silver nanoparticles on the surface of that polymeric coating. In the end, we analyzed its electrocatalytic activity in the electrochemical oxidation reaction of hydrazine," Mirqassem concluded.
