A sensitive method for the determination of pyrethorid cyphenothrin by differential pulse adsorptive stripping voltammetry at a hanging mercury drop electrode (HMDE)(pH6.0) was described. The cyclic voltagramms demonstrate the adsorption of these compounds at the mercury electrode. A symmetric study of the various operational parameters that affect the(More)
A rapid and sensitive liquid chromatography–tandem mass spectrometric (LC–MS/MS) assay method has been developed and fully validated for the quantitative determination of pitavastatin in human plasma. A pitavastatin stable labeled isotope (pitavastatin d4) was used as an internal standard. Analyte and the internal standard were extracted from human plasma(More)
A polymerized film of glycine (Gly) was prepared on the surface of carbon paste electrode (CPE) through the cyclic voltammetry (CV) technique. A novel biosensor for the determination of dopamine (DA) has been constructed based on horseradish peroxidase (HRP) and multiwalled carbon nanotubes (MWCNTs) immobilizing on Poly (Gly)/CPE through silica sol-gel(More)
The dicarboximide fungicide procymidone was studied systematically by using direct current polarography, cyclic voltammetry, differential pulse polarography (DPP), controlled potential electrolysis, and millicoulometry in the universal buffer medium with dimethylformamide as the solvent. Procymidone exhibited a single well-defined polarographic wave in the(More)
A novel analytical reagent, 4-(2-hydroxyphenylethamino)benzene-1,3-diol was synthesized for determination of nickel(II) in biological samples and plant materials by extractive differential pulse polarography. The analysis of nickel(II) was carried out by extracting the nickel(II)-(4-(2-hydroxyphenylethamino)benzene-1,3-diol) complex from chloroform prior to(More)
A sensitive method for the determination of the herbicide pindone by adsorptive stripping voltammetry using a hanging mercury drop electrode at pH 4.0 was described. The cyclic voltammogram of pindone demonstrates that compound was adsorbed at the surface of mercury electrode, and the overall reduction process was under controlled diffusion. The adsorptive(More)
