This method was specifically developed by Danish chemist, Johan G.C.T. Kjeldahl, in 1883 to determine the nitrogen contents in organic and inorganic substances (like foodstuffs, fertilizers, wastewater, soil, feed, grain, and other substances). This method is also used for estimating the protein...
Nitrate concentration limit over which negative and positive interference is significant was quantified at 400 mg L. Consequently, as this study demonstrates, the Semi-Micro-Kjeldahl method is applicable for the majority of water and wastewater samples....

Kjeldahl method (KM) and elemental analyzer method (EA) are commonly used in measuring TN. Their difference, however, is often overlooked. A comparative study on the two methods is conducted by analysis of TN in nearly 100 samples from the sediment sequence of Gouchi, a salt lake in North...
Mercury is used as catalyst; other catalysts which were tried interfered in the titration. Digestion and titration can be done in the same vessel on the micro scale, but a suitable vessel remains to be designed for this to be achieved on the semi-micro scale. The method is not applicable ...
