Guidance of measurement methods and test procedures. Basic tests for polarization-maintaining optical fibres1 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), an enrichment step by amalgamation of the Hg on, for example, a gold platinum adsorber is used.
