Water quality - Determination of mercury - Method using atomic fluorescence spectrometry

ISO 17852:2006 specifies a method for the determination of mercury in drinking, surface, ground and rain water using atomic fluorescence spectrometry. It may be applied to industrial and municipal waste water after an additional digestion step under appropriate conditions. The potential linear dynamic range is approximately 1 nanogram per litre to 100 micrograms per litre. In practice, the working range is often from 10 nanograms per litre to 10 micrograms per litre.Samples containing mercury at concentrations higher than the working range can be analysed following appropriate dilution of the sample. The method detection limit will be dependent on the selected operating conditions and calibration range. With high purity reagents, a method detection limit of less than 1 nanogram per litre is obtainable.The relative standard deviation is typically less than 5 % for concentrations greater than twenty times the method detection limit. The sensitivity of this method is dependent on the selected operating conditions.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
