[Method of determination of ammonia in the air].
The method for determination of ammonia in the air that has been used so far, based on the reaction with Nessler reagent, is outdated. In this method the final colour solutions are not non-ideal solution (there occurs turbidity), which may result in smaller accuracy of determination. Besides this method is not sufficiently specific. A newly-worked out method for determining ammonia in the air is based on spectrophotometric measurement of the green product of ammonium ions reaction with sodium hypochlorite and sodium salicylate. This method is more sensitive, precise and specific than the method for determination with Nessler reagent.
