工作场所空气 - 通过电感耦合等离子体原子发射光谱法测定空气中颗粒物中的金属和准金属 - 第2部分:样品制备

[中文适用范围]： 本文件规定了许多合适的方法，用于从使用 ISO 15202-1 中规定的方法收集的空气颗粒物样品中制备测试溶液，以便随后使用 ISO 15202-3 中规定的方法通过 ICP-AES 测定金属和准金属。 它包含有关方法对于已设定限值的金属和准金属测量的适用性的信息。 该方法还可用于测量一些尚未设定限值的金属和准金属，但在这种情况下没有提供有关其适用性的信息。 注：本文件中描述的样品制备方法通常适用于 ICP-AES 以外的分析技术，例如 ISO 8518[5] 的原子吸收光谱法 (AAS)，并且附件 B 中指定的方法适用于进行比较测量具有可溶性金属或类金属化合物的限值。 当进行测量以与总金属和准金属及其化合物的限值进行比较时，可以使用附录 C 至 H 中规定的一种或多种样品溶解方法。 有关各个方法的适用性的信息在指定该方法的附件范围中给出。 以下是已设定限值且适用本文件中指定的一种或多种样品溶解方法的金属和准金属的非排他性列表（参见参考文献[14]和[15]）。 然而，没有关于任何指定样品溶解方法对斜体元素的有效性的信息。 铝钙镁硒钨锑铬锰银铀砷钴汞钠钒钡铜钼锶钇铍铪镍钽锌铋铟磷碲锆 硼铁铂铊铯铅钾锡镉锂铑钠钛汞蒸气和三氧化二砷蒸气未使用中规定的采样方法收集 [外文原描述]： This document specifies a number of suitable methods for preparing test solutions from samples of airborne particulate matter collected using the method specified in ISO 15202‑1, for subsequent determination of metals and metalloids by ICP‑AES using the method specified in ISO 15202‑3. It contains information about the applicability of the methods with respect to the measurement of metals and metalloids for which limit values have been set. The methods can also be used in the measurement of some metals and metalloids for which limit values have not been set but no information about its applicability is provided in this case. NOTE The sample preparation methods described in this document are generally suitable for use with analytical techniques other than ICP‑AES, e.g. atomic absorption spectrometry (AAS) by ISO 8518 [5] and ISO 11174 [10] and inductively coupled plasma mass spectrometry (ICP‑MS) by ISO 30011 [11] . The method specified in Annex B is applicable when making measurements for comparison with limit values for soluble metal or metalloid compounds. One or more of the sample dissolution methods specified in Annexes C through H are applicable when making measurements for comparison with limit values for total metals and metalloids and their compounds. Information on the applicability of individual methods is given in the scope of the annex in which the method is specified. The following is a non-exclusive list of metals and metalloids for which limit values have been set (see References [14] and [15]) and for which one or more of the sample dissolution methods specified in this document are applicable. However, there is no information available on the effectiveness of any of the specified sample dissolution methods for those elements in italics. Aluminium Calcium Magnesium Selenium Tungsten Antimony Chromium Manganese Silver Uranium Arsenic Cobalt Mercury Sodium Vanadium Barium Copper Molybdenum Strontium Yttrium Beryllium Hafnium Nickel Tantalum Zinc Bismuth Indium Phosphorus Tellurium Zirconium Boron Iron Platinum Thallium Caesium Lead Potassium Tin Cadmium Lithium Rhodium Titanium ISO 15202 is not applicable to the determination of elemental mercury or arsenic trioxide, since mercury vapour and arsenic trioxide vapour are not collected using the sampling method specified in ISO 15202‑1.
