水质.感应耦合等离子体光学发射光谱法(ICP-OES)测定选取的元素

[中文适用范围]： 本标准规定了不同类型水（如地下水、地表水、原水、饮用水和废水）中下列元素的溶解元素、颗粒结合元素（“颗粒”）和元素总含量的测定方法：铝、锑、砷、钡、铍、铋、硼、镉、钙、铬、钴、铜、镓、铟、铁、铅、锂、镁、锰、钼、镍、磷、钾、硒、硅、银、钠、锶、硫、锡、钛、钨、钒、锌和锆。 考虑到特定的和额外发生的干扰，这些元素也可以在水、污泥和沉积物的消解物中测定（例如，ISO 15587-1或ISO 15587-2中规定的水消解物）。 该方法适用于废水中颗粒物的质量浓度低于 2 g/l。 如果可以证明额外发生的干扰被仔细考虑和纠正，则该方法的范围可以扩展到其他基质或更高含量的颗粒物。 由用户来证明其适用性。 表 1 给出了所选元素的推荐波长、定量限和重要光谱干扰。 [外文原描述]： ISO 11885:2007 specifies a method for the determination of dissolved elements, elements bound to particles ("particulate") and total content of elements in different types of water (e.g. ground, surface, raw, potable and waste water) for the following elements: aluminium, antimony, arsenic, barium, beryllium, bismuth, boron, cadmium, calcium, chromium, cobalt, copper, gallium, indium, iron, lead, lithium, magnesium, manganese, molybdenum, nickel, phosphorus, potassium, selenium, silicon, silver, sodium, strontium, sulfur, tin, titanium, tungsten, vanadium, zinc and zirconium. Taking into account the specific and additionally occurring interferences, these elements can also be determined in digests of water, sludges and sediments (for example, digests of water as specified in ISO 15587‑1 or ISO 15587‑2). The method is suitable for mass concentrations of particulate matter in waste water below 2 g/l. The scope of this method may be extended to other matrices or to higher amounts of particulate matter if it can be shown that additionally occurring interferences are considered and corrected for carefully. It is up to the user to demonstrate the fitness for purpose.
