Determination of Heavy Metals in Water System of Beijing Urban Area and a Countermeasure to Remove them

Abstract:

In this study, water samples were collected randomly from water system of Beijing urban area and analysed by inductively coupled plasma-atomic emission spectrometry (ICP-AES) method to determine the contents of harmful heavy metals (Hg, Cd, Zn, Cu, Ni, Cr, Sb, As and Pb). The concentrations of detected heavy metals were found between detection limit of the instrument to 387.196 mg/L. Among them, one sample gave a very high concentration of copper element. In order to get rid of this copper ion away, a chelating type fiber was used to treat the water sample. After treatment with chelating fiber, the concentration of copper was lowered to <10^-5mg/L.
