Hydrochloric acid-potassium permanganate and bromine monochloride are examined for the decomposition of methylmercury(II) chloride, Ceresan, phenylmercury(II) borate and thiomersal added to waters. Both procedures give quantitative recovery of mercury. Bromine monochloride has many advantages: blanks are low, the limit of detection (3σ) is 0.06 μg Hg l-1, routine work is simplified because only two reagents are needed and the reaction time is 5-10 min. The reagent also acts as a preservative. Common contaminants (chloride, bromide, sulphide, alcohols, benzene) do not interfere.
