摘要
The method involves passing a determined volume of gaseous mixture through a filter (5) impregnated with sulfamic acid, to retain chloramine and hypochlorous acid. The volume is passed through a filter (4) to retain gaseous nitrogen trichloride. The retained nitrogen trichloride is reacted with a reagent to decompose the nitrogen trichloride into chloride ions, in the presence of water. Ions are reacted with reagents containing respective ferric ions and mercury thiocyanate, to form ferrithiocyanate ions from the chloride ions. The ferrithiocyanate ions are measured by spectrophotometry.
