in present study we determine the zinc and lead levels in human blood samples by differential pulse polarography under optimum experimental conditions (ph=7.5, scan rate=5mv/s and pulse amplitude=50mv) the polarographic reduction peaks of zn and pb were examinedin the -0.72 v and-0.15 respectively. the zinc and lead content can be determined by in comparison with their standard solutions. accor...

The electrochemical behavior of gatifloxacin (GTFX) and its interaction with natural calf thymus DNA (ctDNA) is investigated by differential pulse voltammetry (DPV) on a carbon paraffined electrode. According to the suggested electrochemical equation, a binding constant of 1.7058 x 10(5) (mol L(-1))(-1) and binding sizes s = 3.09 (base pairs) of GTFX with ctDNA are obtained by nonlinear fit ana...

An electrochemical study of several azulene-1-il-methylen-2,2-dimethyl-[1,3]dioxane-4,6-diones compounds was performed by cyclic and differential pulse voltammetry in order to characterize them and establish the influence of donor and acceptor substituents on their electrochemical properties. It was established the number and characteristics of the redox processes for each compound. The compari...

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...

The study of the interaction between DNA and small molecules such as drugs is one of the current general interest and importance. In this paper, the electrochemical investigation of the interaction between some flavonoids such as rutin, quercetin, and hesperidin with dsDNA on the surface of Supramolecular Ionic Liquid grafted on the Graphene Oxide Modified Glassy Carbon Electrode (</s...

Hydrazine has been identified as a carcinogenic mutagenic, hepatotoxic, and neurotoxin material. A metal-organic framework with tetragonal symmetry, DMOF-1 (Zn2(bdc)2dabco) was synthesized by a versatile and facile technique, followed by its efficient development and validation as hydrazine electrochemical sensor. Differential pulse voltammetry (DPV), linear sweep voltammetry (LSV), and c...
