水质.用离子液相色谱法测定已溶解的阴离子.第1部分:溴化物、氯化物、氟化物、硝酸盐、亚硝酸盐、磷酸盐和硫酸盐的测定

[中文适用范围]： ISO 10304的本部分规定了通过液相色谱法测定水中溶解的溴化物、氯化物、氟化物、硝酸盐、亚硝酸盐、正磷酸盐和硫酸盐的方法，例如饮用水、地下水、地表水、废水、渗滤液和海水。 离子。 溴化物和亚硝酸盐的应用下限为 W 0.05 mg/l，氯化物、氟化物、硝酸盐、正磷酸盐和硫酸盐的应用下限为 W 0.1 mg/l。 应用的下限取决于基质和遇到的干扰。 如果对样品进行适当的预处理（例如痕量分析条件、预浓缩技术），和/或如果使用紫外线（使用 UV）检测器（用于溴化物、硝酸盐和亚硝酸盐）。 [外文原描述]： ISO 10304-1:2007 specifies a method for the determination of dissolved bromide, chloride, fluoride, nitrate, nitrite, orthophosphate and sulfate in water, e.g. drinking water, ground water, surface water, waste water, leachates and marine water by liquid chromatography of ions. The lower limit of application is greater than or equal to 0,05 mg/l for bromide and for nitrite, and greater than or equal to 0,1 mg/l for chloride, fluoride, nitrate, orthophosphate, and sulfate. The lower limit of application depends on the matrix and the interferences encountered. The working range may be expanded to lower concentrations (e.g. greater than or equal to 0,01 mg/l) if an appropriate pre‑treatment of the sample (e.g. conditions for trace analyses, pre‑concentration technique) is applied, and/or if an UV detector (for bromide, nitrate and nitrite) is used.
