Characteristics of Ion Concentration in the Atmospheric Particles in Harbin

Article Preview

Abstract:

We analyzed characteristics and concentrations of water-soluble inorganic ions based on fixed routine collection of atmospheric particulate matter (PM10, PM2.5) samples in Harbin during August 2008 and May 2009. The samplers we sampling is produced by Wuhan Tianhong Intelligent Instrument, we analyzed the water-soluble inorganic ions by using Ion Chromatographic (IC, DX120, Diana, USA) and Indicative Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES, Model 5300, Perkin Elmer, USA). The research showed that: SO42-, NO3-, NH4+ were the top three concentrated of the water-soluble inorganic ions ,the average concentrations were 10.3 μg/m3, 5.8 μg/m3, 8.2 μg/m3 respectively during sampling. Ca2+ was higher in the particulate > 2.5μm, while SO42- and NH4+ were higher in the particulate < 2.5μm, the correlation analysis inferred that the main form of SO42- in atmospheric particle was ammonium sulfate.
