Comparison Of Kjeldahl and Microwave Wet Digestion Methods for Determination of Total Nitrogen Content in Soil and Plant Samples

Object description

Determination of nitrogen content in soil and plant material is performed by the conventional Kjeldahl wet digestion followed by steam distillation and titration of ammonium (NH4 +) . Ammonium (NH4 +) determined in this procedure is the most reduced form of nitrogen but this method cannot detect oxidized forms of nitrogen such as nitrate (NO3 -) and nitrite (NO2 -) that might be present in the samples. Furthermore, the Kjeldahl method, despite its various modifications, is still time consuming a...
