Nitrogen cycle is an important biogeochemical process in the environment. Measurement of total nitrogen (TN) is a routine experiment in researches in agriculture, biology and environmental sciences. Kjeldahl method (KM) and elemental analyzer method (EA) are commonly used in measuring TN. Their diffe...
total nitrogen dataKjeldahl-based approachesThere are multiple protocols for determining total nitrogen (TN) in water, but most can be grouped into direct approaches (TN‐d) that convert N forms to nitrogen‐oxides (NOx) and combined approaches (TN‐c) that combine Kjeldahl N (organic N +NH3...
At the end of the study, all cattail plants were harvested for the determination of total Kjeldahl nitrogen and metal concentrations. The results showed that the COD removal efficiency was practically independent of increasing metal loading or a combination of metal loadings during the duration ...
