Abstract
Flow injection analysis system for determination of ammonia in waste water samples was performed.
The determination was based on the Berthelot's reaction. Ammonia reacts in alkaline solution with hypochlorite
the presence of phenol, catalytic amounts of nitroprousside gave an indophenol blue that measured absorbance
value at 630 nm. The calibration graph established was linear over the range of 5.0 – 600.0 μg N/L and the %RSD
of 0.7 % for 300.0 μg N/L (n=19) was obtained. The purpose method has been successfully applied to the
determination of ammonia in waste water sample with the sample throughput of 45 h
