摘　　要：采用二氯甲烷萃取、活性炭吸附、Na_2CO_3/NaHCO_3淋洗液储备液沉淀等预处理方法,有效地除去了油田灌注污水样中的有机物质和可能存在的高含量的钙镁离子,进而用离子色谱法同时测定了Cl^-、NO_3^-、SO_4^(2-)三种离子,相对标准偏差分别为0.06、4.6、2.2,NO_3^-、SO_4^(2-)离子的加标回收率分别为97.9％和97.1％。In accordance with the characteristics of much more organic compound contents effective in the waslewater of oil field,this paper discussed the elimination of organic compounds by the pretreatment of CH2 C12 extraction and activated carbon adsorption.Moreover,this paper also discussed the determination of Cl-,NCK,SO42-by ion chromatography.The satisfied result was obtained.
