Spectroscopic Determination of Heavy Metal Concentrations in Tap Water for Health Benefits

摘要

This study was aimed to measure concentration of six heavy metals: Cadmium(Cd), Chromium(Cr), Copper(Cu), Lead(Pb), Nickel(Ni), and Zinc(Zn) at subppm levels in tap water using Inductively Coupled Plasma-Optical Emission Spectrometry. Results showed that only the heavy metals Cd and Zn present in studied samples reaching maximum average value of 0.0005±0.0002 ppm and 0.0050±0.0010 ppm, respectively. However, the maximum levels of the concentration of the both detected heavy metals did not reach the maximum limit allowed for human health. The rest of the heavy metals that underwent test in this research work were under the limit of detection method.
