| 摘 要： | 针对离子色谱法与离子选择电极法测定地面水样品中氟化物存在一定偏差的现象，此文较详细地研究了影响测定结果的干扰因素，确证ＣＯ３＾２－，ＨＣＯ３＾－均能产生正干扰，其干扰程度与干扰物质的含量成正比，为消除基体的干扰，可采用标准加入法。

| Abstract: | The factors influencing the determination of fluoride in ground water by ion chromatography was studied in detail. It has been proved that contents of CO2-3,HCO-3 in water are the main interferences and the interfering extent is in derect proportion to their contents.Standard addition method can be applied very effectively to eliminate the influences. |
