摘要
选用ＨＰＩＣ－Ａｓ－４Ａ离子色谱分离柱及ＡＦＳ－２纤维抑制双柱系统，使用Ｎａ２ＣＯ３－ＮａＨＣＯ３双组份为淋洗液，采用电导检测器，利用峰高、峰面积法定量分析。Ｆ－（０．０２～０．７）、Ｃｌ－（０．３～１．０）、ＮＯ－３（０．０５～０．２）、ＳＯ２－４（０．６～２．０ｍｇ／Ｌ）范围内，其校正曲线有很好的线性关系，相关系数均在０．９９８４～０．９９９８。应用此方法分析了大气总悬浮颗粒物和粉煤灰陶粒试样中可溶性阴离子，获得了可靠的分析结果。ＮＯ－３、ＳＯ２－４回收率分别为９３．９０％、１０１．９％。
his article describes
the simultaneous determination of trace F-Cl-NO-3SO2-4 anion components by ion
chromatography.HPICAS4A column and a fiber suppressor column were used with
Na2CO3NaHCO3 solution as the eluent and electric conductance detector.The linear calibration
curves are in the range(mg/L) of F-(0.020.7)Cl-(0310)NO-3(00502)SO2-4(0620) with r
0.998409998.The retention times are 1.20 ,2.40,8.60 ,10.28 min respectively.The method has
been used for the determination of TSP flyash,coal and ceramics with satisfactory results.
