离子色谱法测定水中阴离子的方法研究

通常所用化学分析法和离子选择电极法测定离子的过程繁琐且费时，而采用离子色谱法同时测定水中F ^-、C1^-、NO2^-、SO4^2-和NO3^-离子，具有选择性好、灵敏度高、分析速度快等优点。目前已经广泛应用于、水文、地质、石油化工、医疗卫生等领域。采用测定方法的相关性好（r〉0．999），检出限在0．02mg／L—0．09mg／L之间，线性范围宽，精密度高，样品回收率高，取得了满意的结果，具有较高的使用价值。

Ion Chromatography Method Of Anions In Water

The process, in which chemical analysis and ion-selective ion electrode methods are generally applied, is verbose and time consuming. Whereas, the application of ion chromatography to Simultaneous determination of F^-, C1^-, NO2^-, NO3^-, SO4^2- achieves good selectivity, high sensitivity, and speedy analysis, etc. It has been widely used in hydrological, geological, petrochemical, medical and public health. Applying this, the determination of the relevance of this article is good （r〉 0.999）, between the detection limit in 0.02mg/L-0.09mg/L ; the linear range is wide; the precision sample rate are high, achieving satisfactory results with higher value in practice.
