ISO 14403-1:2012规定了未稀释样品中氰化物浓度为2μg/l至500μg/l(以氰化物离子表示)的各类水中氰化物(如地面、饮用水、地表水、渗滤液和废水)的测定方法。可通过改变操作条件改变应用范围,例如稀释原始样品或使用不同的进样量。
ISO 14403-1:2012中描述了20μg/l至200μg/l的合适质量浓度范围。
分析海水时,试剂和校准溶液的灵敏度和适应性可能会发生变化,以适应样品的盐度。
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.
