Polarographic 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 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 Analysis of Quetiapine in Pharmaceuticals
The voltammetric behaviour of quetiapine (QTP) was studied using direct current (DCt), differential pulse (DPP) and alternating current (ACt) polarography. The drug manifests cathodic waves over the pH range of 6 – 11.8. The waves were characterized as being irreversible, diffusion-controlled with limited adsorption properties. At pH 8, the diffusion current-concentration relationship was recti...
متن کاملDetermination of Copper (II) and Palladium (II) by Polarographic Methods
Schiff base 2–Hydroxy–5–methoxy Benzaldehyde – Tris [HMBT] Ligand is a new chromogenic reagent have not been used so far for the determination of copper and palladium in trace quantities. Effect of p H on wave height for COPPER[HMBT] PALLADIUM –[HMBT] systems have been studied at p H 7-8.5 and 8.5-11.5 for Copper and Palladium respectively in 0.1 m molar NaNo3 and 0.002 % Triton –x–100 which in...
