改进离子色谱法测定水中氟含量

Determination of F- in water by improved chromatography of ions

离子色谱法测定水中氟离子含量，由于水中负峰的干扰，会存在较大偏差，通过在样品中添加淋洗液，可消除水的负峰，使测定结果更准确可靠。

Because the negative peak of water disturb determination of F- in water with ion chromatography method, it produces wide windage. The negative peak of water will be eliminated by adding eluent solvent to sample . The determination result will accurate and credibility.
