Measurement of un-ionized ammonia in complex mixtures.


The toxicity of un-ionized ammonia, NH3 (aq), in anaerobic digestion of high-nitrogen wastes has been researched extensively. Previous estimates of NH3 (aq) concentration have relied on a simple speciation approach, based only on the acid dissociation constant and the sample pH and total ammonia concentration. The distinction between concentration and… (More)
