In this method the
sample is vaporized and burned in a
stream of air, and the oxidation completed by passing
over quartz particles maintained at a temperature of 950 to 1000 degree C. The combustion products are then passed
through hydrogen peroxide which
absorbs the sulfur
as sulfuric acid and
the chlorine as hydrochloric acid. The absorbent
is then analyzed for total
acidity and for chloride ion. The procedure for
the determination of
chlorine is included
only for correcting
the sulfur content
and the method is not
recommended for the determination
of chlorine alone.
