摘　　要：利用傅立叶变换红外光谱仪,固体制样方式.对北京市中关村地区的气溶胶样品中的无机组成进行了分析,并对气溶胶样品中的SO_4^(2-).NH_4^+和NO_3^-进行了定量测定.为检验FTIR测定法的可靠性,将FTIR法与离子色谱的测定结果进行了对照分析,结果表明,SO_4^(2-)和NH_4^-的FTIR测定结果与离子色谱有较好的相关性.Using quantative analysis of fourier transform infrared spectroscopy (FTIR), inorganic compounds of SO42- , NH4+ and NO3- in ambient aerosol particles prepared by pre ssing into KBr pellet were studied. In order to validate the FTIR method, ion chromato-graphy(IC) was used as a contrast. It was found that FTIR measurement results for sul-fate and ammonium were consistant with data from IC.
