离子色谱法测定董铺水库水中阴离子

Determination of Anion in Dongpu Reservoir by Ion Chromatography

为了了解董铺水库水中阴离子含量是否超标,使用离子色谱法对其中4项常见的阴离子指标(F^-、Cl^-、NO_3^-、SO_4^(2-))进行了同时检测,测定结果验证了该检测方案具有较高的可靠性和准确性。对董铺水库的水质检测结果进行测定,得到F^-、Cl^-、NO_3^-和SO_4^(2-)的含量分别为0.285mg/L、8.528mg/L、3.893mg/L及21.348mg/L,表明董铺水库水质较好,符合地表水环境质量标准中相应技术要求。

In order to determine whether anion concentrations exceed bid in Dongpu reservoir,determi- nation of anion（F^-,Cl^-,NO3^-,SO4^2-） by ion chromatography is adopted, and thus verify the reliable accuracy of ion chromatography. The content of F^-,Cl^-,NO3^- and SO4^2-in Dongpu reservoir was 0. 285 mg/L,8. 528 rag/L, 3. 893 mg/L and 0. 285 mg/L, respectively. The conclusion is drawn that the water quality in Dongpu reservoir is good, and accords with the corresponding technical requirements of environmental quality standards for surface water, after analysis of monitoring results of water quality in Dongpu reservoir.
