Determination on Metal Elements and Water-Soluble Anion in PM_2.5

Abstract:

Samplings of PM_2.5 used to determine water-soluble anions were obtained from four representative sites of Hefei. There are High-tech zone, Binhu new area, Hupo villa, Dongpu reservoir. The other samplings of PM_2.5 used to determine metal elements came from four kinds of domestic waste combustion. There are paper, plastic, cotton, rubber. In this article, anions were detected by ion chromatography (IC). It was found that the main anions in PM_2.5 are NO₃^-, SO₄^2-. Metal elements were detected by inductively coupled plasma-atomic emission spectroscopy (ICP-AES). Fe, Mn, Zn, Cu, Cd, Cr six kinds of metal elements were detected in this article. The main metal elements in samplings of PM_2.5 are Fe and Cu element. The concentrations of Cd and Cr elements are lower in four domestic waste burning.
