Anodic Stripping Voltammetric Determination of Mercury (II) using Lectin-modified Carbon Paste Electrode

Anodic Stripping Voltammetric Determination of Nitrite Using Carbon Paste Electrode Modified with Chitosan

A simple method for anodic stripping voltammetric determination of nitrite using carbon paste electrode modified with biomolecular chitosan, is described. In this method, the electrode is activated electrochemically by scanning 5 replicates over the potential range from +500 to +1400 mV immersing in 0.5 M HCl solution. Following this step, the nitrite sample containing 0.1 M KCl is pre-concentr...

Simultaneous Determination of Hg(II), Cd(II), Pb(II) and Zn(II) by Anodic Stripping Voltammetry using Modified Carbon Paste Ionic Liquid Electrode

In the presented study, CuO-CoO-MnO/SiO2 nanocomposite was synthesis by Cu(II), Co(II), Mn(II), with 1:1:1 mole ratio and Tetraethyl orthosilicate. azo–azomethine 1-(3-imino-4-hydroxophenylazo-4-nitrobenzene)-4-methyl phenol (L) was synthesized and used as a ligand for capturing the metal ions. Also, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide was applied as the i...

Voltammetric determination of cysteine at a carbon paste electrode modified with Cu(II)-salen complex

The electrochemical behavior of a modified carbon paste electrode (MCPE) with N,N′ethylenbis(salicylideneiminato)copper(II) complex ([Cu(II)-Salen]) was investigated as a newsensor for cystein. The Britton-Robinson buffer with pH 5, 10% modifier in electrode, potentialscanning rate of 20 mVs-1 and puls height of 50 mV were used as the optimum condition for thedetermination of cysteine using car...

Stripping Voltammetric Determination of Uranium in Water Samples Using Hg-Thin Film Modified Multiwall Carbon Nanotube Incorporated Carbon Paste Electrode

The variables affecting determination of ultra trace levels of uranium (VI) in aqueous samples by differential pulse cathodic stripping voltammetry were examined in detail using Hg-thin film modified carbon paste and multiwall carbon nanotube (MWCNT) incorporated carbon paste electrode. Carbon paste electrode prepared in the laboratory was modified with Hg thin film and used as the working elec...
