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...
Other parameters analyzed in the water samples included total suspended solids (TSS), ammonia, chloride, chlorophyll a, fluoride, nitrite + nitrate, total Kjeldahl nitrogen (TKN), soluble reactive phosphorus (SRP), total dissolved phosphorus (TDP), specific conductance and turbidity. The ISCO ...
NITROGENRemoving nutrients from wastewater is essential because high concentrations in aquatic systems lead to severe eutrophication problems, the most common impairment of surface waters such as lakes and oceans. Total phosphorus (TP) and total Kjeldahl nitrogen (TKN) were removed from m...
There 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) and nitrite+nitrate (NO2+NO3‐N). ...
Indicators of biological productivity (chlorophyll a, volatile suspended solids, and total Kjeldahl nitrogen) were higher in the Blue Earth and Minnesota Rivers compared to the Le Sueur River, which may signal a connection between higher biological activity and increased MeHg concentrations.
