Danger
When dealing with acidic solutions that contain cyanide, there is dan-
ger of poisoning by released hydrocyanic acid. It is imperative to add
the alkaline reagent MZ/NH3/CN to any sample in order to raise the pH
value of the sample to > 10 and prevent the release of hydrocyanic acid.
Carry out cyanide determinations in acidic media with special safety
measures only, e.g. in a fume hood.
