Determination of clenbuterol with differential pulse anodic stripping voltammetry technique at tungsten disulfide-modified electrode

Differential pulse anodic stripping voltammetric determination of traces of copper with a tobramycin-Nafion modified electrode.

A Nafion-modified glassy carbon electrode incorporated with tobramycin for the voltammetric stripping determination of Cu2+ has been explored. The electrode was fabricated by tobramycin containing Nafion on the glassy carbon electrode surface. The modified electrode exhibited a significantly increased sensitivity and selectivity for Cu2+ compared with a bare glassy carbon electrode and the Nafi...

Determination of mercury at a dithizone-modified glassy carbon electrode by anodic stripping voltammetry.

SW Anodic Stripping Voltammetry Determination of Copper with New Tape of Modified GC Electrode

The analysis of Cu(II) by anodic stripping voltammetry using a Nafion-modified glassy Carbon electrode incorporated with Cu-DPABA complex (DPABA is Methyl 3,5bis{bis-[(pyridin-2-yl)methyl]amino}methyl)benzoate ) (Cu-DPABA–NA/GCE) is described. Cu(II) was accumulated in Hac-NaAc buffer pH=4 at potential of -0.3 V (vs. Ag/AgCl ref. electrode) and then determined with SWASV. Under the optimum cond...

Trace determination of cadmium in water using anodic stripping voltammetry at a carbon paste electrode modified with coconut shell powder

Background: Increasing awareness on the environmental impact of heavy metals has increased a considerable interest in the determination of metals in natural water bodies. The present paper describes the development and electrochemical application of carbon paste electrode modified with fibrous part of coconut shell for the determination of cadmium in water samples. Methods: Determination was ca...

Determination of Tl(I) Ions in Homeopathic Drugs by Differential Pulse Anodic Stripping Voltammetry

Objectives: The present study is focused on the determination of thallium (I) ions in homeopathic drugs. Methods: The determination was carried out using the Differential Pulse Anodic Stripping Voltammetry (DPASV) technique coupled with the flow-injection measuring system (FIA-DPASV). Results: The thallium content was analyzed in two commercial homeopathic preparations (Thallium aceticum 5CH an...
