摘　　要：本文使用了一种利用离子色谱法同时测定地表水中氟化物、氯化物、硝酸盐和硫酸盐的方法。实验数据充分证明,该方法在多种类型的水体中对氟化物、氯化物、硝酸盐和硫酸盐均展现出较好的线性关系。此外,通过样品加标回收率测试可知,样品的加标回收率稳定在94.8%~106.0%之间。在6次重复测试中,相对标准偏差均保持在4%以下,进一步验证了该方法的稳定性和可靠性。该方法不仅操作简便,而且具备良好的准确性,为地表水中多种离子的测定提供了一种有效的技术手段。This article used an ion chromatography method to simultaneously determine fluoride,chloride,nitrate,and sulfate in surface water.Experimental data fully prove that this method shows a good linear relationship with fluoride,chloride,nitrate,and sulfate in various types of water bodies.In addition,through the sample spiking recovery rate test,it is known that the spiking recovery rate of the sample is stable between 94.8%and 106.0%.In six repeated tests,the relative standard deviation is kept below 4%,which further verifies the stability and reliability of this method.In summary,this method is not only easy to operate but also has good accuracy,providing an effective technical means for the determination of various ions in surface water.
