Freshwater data from Trussel (1972).
1
Seawater values from Bower & Bidwell (1978). Salinity for Seawater values = 34% at an ionic strength
2
of 0.701 m.
FOR EXAMPLE:
A fresh water sample at 20°C has a pH of 8.5 and the test result is 1.0 ppm as Total
Ammonia.
1.
The percentage from the table is 11.18% (or 0.1118).
2.
1 ppm Total Ammonia x 0.1118 = 0.1118 ppm Unionized Ammonia
