Anodic stripping voltammetry: affordable and reliable alternative to inductively coupled plasma-based analytical methods

Abstract

Water is one of the main sources of metals income of the human body, and therefore, it is important to constantly monitor sources of drinking water to avoid adverse health risks. The natural concentration of metals in the water might vary. It depends on the metal concentration in the soil, the underlying geological structures, the acidity of water, its humus content, and particulate matter concentration. In the present study, direct determination of metals such as Mn, Zn, Cd, Pb, and Cu was carried out from surface and underground water using anodic stripping voltammetry at a hanging mercury drop electrode. The results from the determination of metals using the studied method and inductively coupled plasma-atomic emission spectrometry for Mn, Zn, Cd, and Cu, and inductively coupled plasma-mass spectrometry for Pb were compared and found to be in good agreement.
