Resin Bead Detection and Spectrophotometric Determination of Phenylhydrazine Using Inorganic Reagents

Sensitive and Selective Determination of Phenylhydrazine in the Presence of Hydrazine at a Ferrocene Monocarboxylic Acid Modified Carbon Nanotube Paste Electrode

“…Because this substance and its derivatives are applied in such a variety of different fields and has been recognized as a carcinogenic and hepatotoxic agent, their quantitative determination is of great analytical importance, attracting the interest of many researchers. Different methods for the determination of hydrazine and its compounds, such as flow injection analysis with fluorimetric (Ensafi and Rezaei 1998) and chemiluminescence (Song, Wang, and Zhao 2001;Safavi and Baezzat 1998;Lv, Huang, and Zhang 2001) detection, potentiometric (Mo et al 2000;George, Nagaraja, and Balasubramanian 2007), spectrophotometric (Hasan 1988;Ortega-Barrales et al 1997;Ensafi and Naderi 1997;Afkhami and Assl 2001), and capillary electrophoresis (Siangproh et al 2005) methods have been described in literature. Electroanalytical techniques seem to provide direct and efficient methods for the detection of hydrazine and its derivatives.…”

A new induction period based reaction rate method for determination trace amounts of phenylhydrazine in water samples

“…Different classical and instrumental methods have been reported for determination of phenylhydrazine in various samples. These include spectrophotometry [6][7][8][9][10], titrimetry [11], and gas chromatography [12]. These methods either lack sufficient sensitivity or are time consuming.…”

A Spectrophotometric Flow Injection Method for Determination of Ultratrace Amounts of Phenylhydrazine by Its Inhibition Effect on the Reaction of Thionin and Nitrite

“…Several methods have been reported for the determination of phenylhydrazine. ese include spectrophotometry [2][3][4][5], chromatography [6], H-point standard addition method [7,8], kinetic methods [9][10][11][12], and electrochemical methods [13][14][15][16]. According to our best knowledge, this is the �rst �ow injection (FI) method proposed for the determination of phenylhydrazine.…”
