| Abstract: | When we determinate the concentration of ammonia nitrogen by adding the Nessler's reagent, we add different quality alkali to it, this takes big effect on the Nessler's reagent method, after many experiments, we think that it is the fittest to add 0.5ml, 25% sodium hydroxide (NaOH) neutralizing 10ml boric acid. |
