“…The response time measured in amperometric determination is 1 s or less to 90% of the full signal. These analytical parameters are comparable with results reported for analytical determination of hydrazine at the surface of different modified electrodes [31 -34] or better than a GC electrode modified with a thin film of Cobalt pentacyanonitrosylferrate (CoPCNF) [5], graphite electrode modified with N,N',N'',N'''-tetra methyl-tetra 3,4-pyridoporphyrazino cobalt(II) [9] GC electrodes modified with Caffeic acid [10], pyrocatechol violet [11], chlorogenic acid [12], GC and conducting-glass electrode modified with poly(cobalt-tetraaminophthalocyanine) [35], Pt electrode modified with 4-pyridyl hydroquinone [36], Nafion / ruthenium (III) chemically modified electrode [37], screen-printed electrode modified with cobalt phthalocyanine and ruthenium cyanide coating [38 ], Prussian Blue modified GC electrode [39], or GC electrode modified with 3,4-dihydroxy benzaldehyde [40].…”
