Anodic stripping voltammetric determination of Pb, Cd, Zn and Cu in blood samples of 132 children was developed. The children's ages range was between 6 months and 6 years and the samples were collected from different areas of Ibb governorate (Yemen). We used anodic stripping voltammetry for analyzing and determination of cited metals in the blood of all children. Large variation in the results...

Anodic behavior of aripiprazole (ARP) was studied using electrochemical methods. Charge transfer, diffusion and surface coverage coefficients of adsorbed molecules and the number of electrons transferred in electrode mechanisms were calculated for quasi-reversible and adsorption-controlled electrochemical oxidation of ARP at 1.15 V versus Ag/AgCl at pH 4.0 in Britton-Robinson buffer (BR) on gla...

In the present paper, we report on the use of adsorptive transfer stripping technique in connection with chronopotentiometric stripping analysis for metallothionein determination and of differential pulse anodic stripping voltammetry for lead detection in tissues of wild perch (Perca fluviatilis, n = 6) from the Svratka River in Brno, Czech Republic. Primarily, we determined the content of MT i...

A Sensitive and precise differentialpulse stripping voltammetric method at static mercury dropping electrode (SMDE) has been applied to measure zinc(II) by anodic stripping at pH∼4 and aluminum(III) by adsorptive cathodic stripping mode in presence of 1×10M N,N` -bis-2-hydroxyethyl-2-amino-ethane sulphonic acid (BES) buffer at pH~7.1 and 2×10 M of alizarin red S as a ligand in drinking water sa...

An approximate but general theoretical treatment for reversible and irreversible stripping polarographic systems is presented. The treatment is based on the development of an average current (i), which at plating times exceeding 15 s. is analogous to the instantaneous current in d-c. polarography. Plots of i vs. (E E*) are generated for reversible and irreversible waves and are discussed for th...

Copper and arsenic have been analysed in refined beet sugar at the microgram kg-1 level by anodic stripping voltammetry (copper) and cathodic stripping voltammetry (arsenic) in the differential-pulse mode (DPASV and DPCSV) at a hanging mercury drop electrode (HMDE). DPCSV measurements of arsenic are based on its accumulation onto the HMDE as an intermetallic Cu-As compound followed by the reduc...

METHODS: The quantitative methodology was based on ELISA in poly(dimethylsiloxane)-gold nanoparticle composite microreactors. CdTe and ZnSe quantum dots were bioconjugated with antibodies for sandwich immunoassay. After the CdTe and ZnSe quantum dots were dissolved, Cd and Zn were detected by square-wave anodic stripping voltammetry to enable the quantification of the two biomarkers. The two bi...

The heavy metals Cd, Pb, Zn, Ni and Mo were determined in 27 samples of medicinal herbs taken from various places in Bielsko Biata and the neighbouring area. Samples were digested by the wet method in a microwave oven. Flame AAS and differential pulse polarography (anodic and stripping voltammetry) were used for determination of these metals. Oriental tobacco (CTA-ATL-1) as the certified refere...
