SO3
or H2SO4 is absorbed into a solution of propan-2-ol and reacts with
barum chloranilate. Chloranilate ions are measured to determine SO3
concentration |

The SO3 or H2SO4 in the gas sample
is absorbed as sulphate ions (SO42-) in an aqueous solution of
propan-2-ol in water. The solution is passed through a bed of barium chloranilate.
The acid chloranilate ions are measured in a continuous flow photometer. By maintaining a
constant ratio of flow rates for the gas and the propan-2-ol absorbing solution, the
concentration of acid chloranilate ions can be directly related to the sulphate ion
concentration in the absorbing solution, and hence the SO3 concentration in the
gas. |
