Voltammetric Study of the Redox Current Peaks of Pb(II) Mediated by GCE in Normal Saline

Abstract

Lead ion of sulfate was studied electrochemically analysis, using cyclic voltammetric technique by glassy carbon electrode (GCE) in normal saline solution (0.9%NaCl). The results of the study have been found oxidation and reduction current peaks of lead ion in normal saline at -550 mV and -650mV respectively. It was studied the electrochemical properties of the redox current peaks of Pb(II) with different reagents such as glucose, uric acid, urea and ascorbic acid in normal saline. The redox current peaks of Pb(II) were enhanced through using each of glucose, uric acid and urea, but in ascorbic acid the reduction current peak was reduced. Also, the other phenomena of the reduction current peak of Pb(II) was disappeared when using blood as an electrolyte because the lead ions act as oxidant pollutant in blood medium.

Voltammetric study of saffron in blood mediated by modified glassy carbon electrode (GCE) with carbon nanotube (CNT/GCE)

“…Saffron reduced the cross-section area, media thickness, and elastic lamellae number of the aorta. Nutritional saffron prevented BP increases and remodeling of the aorta in hypertensive rats [7]. Saffron has biological activities including antihumoral, cytotoxic, hypolipidemic, anti-inflammatory, etc.…”
