Polarographic Behaviour and Analysis of Permethrin
The electrochemical reduction behaviour of Permethrin has been carried out, by employing d.c. polarography, cyclic voltammetry (CV) and differential pulse polarography (DPP) in the supporting electrolytes of the pH ranging from 2.0 to 12.0. The nature of electrode process was studied, the number of electrons was evaluated and the reduction mechanism was proposed. Kinetic parameters such as tran...
متن کاملPolarographic reduction of adenine and cytosine residues in denatured DNA.
Polarographie reduction of adenine and cytosine moieties in denatured DNA was followed by means of differential (derivative) pulse polarography. The measurements of the reduction currents yielded by samples of denatured DNA differing in guanine+cytosine (G + C) content showed that both cytosine and adenine residues were reduced in DNA in the pH range of 6.0 —8.7. The con tribution of their red...
متن کاملPolarographic Methods of Analysis
The polarographic method invented by J. Heyrovsk over 40 years ago has been associated with many successful achievements in many branches of physical and analytical chemistry, particularly in electrochemistry. Following the construction of the polarograph (with the excellent properties of Kuera's dropping mercury electrode incorporated) by Heyrovsk and Shikata, recording the current—voltage cur...
متن کاملPolarographic Behaviour of Salicylaldehyde-2-Pyridylhydrazone and Its Copper(ll) Complex*
The polarographic behaviour of salicylaldehyde-2-pyridylhydrazone (SAPH) has been studied in aqueous buffer solution containing 40% ethanol using DC and DP polarographic methods. In the pH range 1.8--7.5 the observed single irreversible reduction wave is assigned to the splitting of the N N bond and reduction of C = N centre. In alkaline medium, a second wave appears at a more negative potentia...
متن کاملPolarographic determination of malononitrile.
A procedure is proposed for the determination of malononitrile by differential pulse polarography in methanolic 0.1M tetraethylammonium iodide/0.001M tetramethylammonium hydroxide as the supporting electrolyte. In this medium malononitrile is chemically converted into an electroactive species. With close control of timing of the steps in the procedure the error of the method is +/-1.5% in the c...
