- Scope
- This International Standard specifies two methods for the determination of mercury in drinking, surface,ground, rain and waste water after appropriate pre-digestion. For the first method (described in Clause 6), anenrichment step by amalgamation of the Hg on, for example, a gold/platinum adsorber is used. For the methodgiven in Clause 7, the enrichment step is omitted.
