Abstract

Hydrazines are well-known for their diverse biological properties but especially for their toxicity. An amperometric hydrazine sensor was developed at multi-walled carbon nanotubes (MWCNT) and iron tetrasulfonated phthalocyanine (FeTsPc) composite modified electrode for the first time. The TEM and UV-Vis spectroscopy results revealed the successful formation of MWCNT/FeTsPc composite. Compared with the response of MWCNT and FeTsPc modified electrodes, the MWCNT/FeTsPc composite showed enhanced oxidation current response with lower overpotential for hydrazine. Under optimum conditions, the amperometric i-t response of hydrazine was linear in the concentration range from 100nML^-1 to 3μML^-1 with the detection limit of 7.6nML^-1. The response time of hydrazine was found as 6s with a high sensitivity of 7.615μA/μML^-1cm^-2.
