Halogens by pyrohydrolysis

Our laboratory provides fluorine, chlorine and bromine determinations in various matrices like bricks, cements, slags, ores, ...

The sample is heated to 1100°C in a tubular furnace. Halogens are carried over by a current of water steam and collected in a sodium hydroxyde solution. The solution is subsequently analyzed by ion chromatography or by fluoride specific electrode.
