The Kjeldahl method or Kjeldahl digestion in analytical chemistry is a method for the quantitative determination of a sample's organic nitrogen plus ammonia/ammonium. (NH3/NH4 ). Without modification, other forms of inorganic nitrogen, for instance nitrate, are not included in this measurement. Using an empirical relation between Kjeldahl nitrogen and protein, it is an important method for indirectly quantifying protein content of a sample. This method was developed by Johan Kjeldahl The Kjeldahl method was introduced in 1883 and consists of three main steps: sample digestion, distillation, and ammonia determination (titration . The most common approved method for water/wastewater is distillation of a sample’s ammonia into an acidic trapping, or absorbing solution. Nitrogen concentrations can then be determined by classical titrimetic, .
