【摘要】 采集了北京市2007年1月总悬浮颗粒物(TSP)、PM10和PM2.5样品,将TSP样品溶解在pH=5.60稀硫酸溶液中,用反滴法测定了颗粒物在酸性条件下的酸度和潜在酸性,评价了实际大气环境下颗粒物对降水酸化的影响.更多还原

【Abstract】 TSP,PM10 and PM2.5 were collected in Beijing in January,2007.The acidity and acidification buffering capacity of particles were measured. TSP samples were dissolved in diluted sulfuric acid(pH=5.60) ,and the retro-titration method was used to get the acidity and potential acidity of particulate matters. The influence of particles on precipitation acidification in the real air environment was also evaluated.更多还原
