在详细分析了硫酸盐和酸式硫酸盐的红外光谱特征的基础上，利用傅利叶变换红外光谱仪，ＫＢｒ压片的制样方式，选择７５０—５００ｃｍ－１作为定量范围，对１９９４年春、夏、冬和１９９５年春季北京中关村地区气溶胶样品中的ＳＯ２－４和ＨＳＯ－４进行了定量测定，ＳＯ２－４和ＨＳＯ－４在大气中的含量分别为２．５６至６０．４μｇ／ｍ３和未检出至５．７μｇ／ｍ３．从而建立了直接测定大气气溶胶中酸式硫酸盐的傅利叶变换红外光谱法．
Based on the detailed analysis of the infrared spectra of sulfates and acid sulfates, the method of sample preparation by Fourier transform infrared spectroscopy and KBr pelleting was used to select the quantitative range of 750-500cm-1. The spring, summer and winter And SO2-4 and HSO-4 in aerosol samples of Beijing Zhongguancun area in the spring of 1995. The contents of SO2-4 and HSO-4 in the atmosphere were 2.56 to 60.4 μg / m3 and were not detected Out to 5.7 μg / m3. Thus establishing a direct Fourier transform infrared spectroscopy method for the determination of acid sulfate in atmospheric aerosol.
