Ammonia determination in wastewater

In this application note, an easy and reliable method for the determination of ammonia in wastewater is introduced. Ammonia was determined by steam distillation followed by colorimetric titration in boric acid with the MultiKjel and Metrohm Eco Titrator, respectively, providing reliable and reproducible results
