标准摘要
[中文适用范围]： ISO 14403的本部分规定了氰化物浓度为2 hg/l至500 Hgy/|的各类水（例如地下水、饮用水、地表水、渗滤液和废水）中氰化物的测定方法。 表示为未稀释样品中的氰化物离子。 应用范围可以通过改变操作条件来改变，例如通过稀释原始样品或使用不同的注射体积。 在 1SO 14403 的这一部分中，描述了 20 hg/l 至 200 hg/li 的合适质量浓度范围。 可以通过灵敏度的可能变化以及试剂和校准溶液对样品盐度的适应来分析海水。 [外文原描述]： ISO 14403-1:2012 specifies methods for the determination of cyanide in various types of water (such as ground, drinking, surface, leachate, and waste water) with cyanide concentrations from 2 µg/l to 500 µg/l expressed as cyanide ions in the undiluted sample. The range of application can be changed by varying the operation conditions, e.g. by diluting the original sample or using a different injection volume. In ISO 14403-1:2012, a suitable mass concentration range from 20 µg/l to 200 µg/l is described. Seawater can be analysed with possible changes in sensitivity and adaptation of the reagent and calibration solutions to the salinity of the samples.
