Analysis on the chemical composition of precipitation in Hefei
摘要
Abstract
To investigate the chemical features of precipitation in Hefei, precipitation samples were collected and analyzed during April to September, 2010. The chemical characteristics of rainwater were discussed. The major anions was SO2-4 , and the major cations were NH4+ and Ca 2+ The ratio of [ SO2-4 ] / [ NO-3] ranged from 1.23 to 6. 33 , it was below 3. 0 in the most cases, this fact suggested that the acid rain in Hefei belonged to sulfuric and nitric acid mixture. No significant correlation was found between the acidity of precipitation and any single ion concentration. The acidity was decided by multiple ions. Significant correlations were observed between SO2-4and NO-3 ,Ca+2 and Mg2+,NH4+ and SO2-4 , NH4+ and NO-3.关键词
