摘　　要：采用盐酸萘乙二胺分光光度法对邢台市空气中的氮氧化物含量进行测定,二氧化氮标准曲线回归方程为y=0.191 4 x+0.003 6,相关系数r=0.999 7。采用甲醛缓冲液-盐酸副玫瑰苯胺溶液分光光度法测定空气中的二氧化硫含量,二氧化硫标准曲线的回归方程为y=0.436 2 x+0.004 5,相关系数r=0.999 9。通过对达活泉公园、邢台工业园区的空气样品进行监测,测得11月氮氧化物和二氧化硫的浓度最高,其中,氮氧化物浓度为0.082 mg/m3(达活泉公园)和0.123 mg/m3(邢台工业园区);二氧化硫浓度为0.116 mg/m3(达活泉公园)和0.139 mg/m3(邢台工业园区)。同时从邢台市的工业结构与布局、传统燃料的使用、汽车尾气和扬尘以及地形气候条件等方面对邢台市大气污染成因进行分析。The content of nitrogen oxides in the air of Xingtai was determinated by naphthyl ethylenediamine dihydrochloride spectrophotometric method. The regression equation of standard curve of nitrogen dioxide is y = 0.191 4 x＋ 0.003 6, r =0.999 7. The content of sulfur dioxide in the air was determined by formaldehyde buffer solution of hydrochloric acid spectrophotometric method. The regression equation of standard curve of sulfur dioxide is y= 0.436 2 x ＋0.004 5, r = 0.999 9. By measuring the air samples of Dahuoquan Park and Xingtai Industrial Park, the results show that the highest concentration of nitrogen oxide and sulfur dioxide is in the air of Xingtai in November. The content of nitrogen oxide is 0.082 mg/m^3 in Dahuoquan Park, which is 0.123 mg/m^3 in Xingtai Industrial Park; the content of sulfur dioxide is0.116 mg/m^3 in Dahuoquan Park and which is 0.139 mg/m^3 in Xingtai Industrial Park. Besides, the causes of air pollution in Xingtai from many aspects, such as its industrial structure and layout, the use of traditional fuels, vehicle exhaust,terrain climate conditions and other reasons were analyzed.
