摘　　要：利用抑制性离子色谱仪对全国各地户外高压绝缘子自然污秽物水溶液中的F-、Cl-、NO3-、SO42-4种阴离子含量进行了分析。定量方法采用标准曲线法。结果表明,污秽物中F-离子含量最低,大多数都小于1 mg/g;SO42-含量远远高于其它3种一价阴离子,基本都超过了100 mg/g,最高的达到了300 mg/g。表明离子色谱法能够准确地测定电缆污秽物中阴离子的种类与含量,具有检测限低,检测范围宽,快速准确的特点。Using self-regenerated chemical suppressed ion chromatography and conductivity detector, the F^-, Cl^-, NO2^- and SO4^2- content in the deposits of natural polluted insulators is analyzed. The calibration curve is used. The result indicates that the content of F^- is the lowest, most of the data are lower than 1 mg/g, but the content of SO4^2- is the highest, most of the data are higher than 100 mg/g, and the highest one reached 300 mg/g. So the suppressed ion chromatography can determine the classes and contents of the ions accurately. It has the characteristics of low detect limit, wide detect range, rapidness and accuracy.
