Popis
BS EN 16169:2012
This standard BS EN 16169:2012 Sludge, treated biowaste and soil. Determination of Kjeldahl nitrogen is classified in these ICS categories:
- 13.030.01 Wastes in general
- 13.080.10 Chemical characteristics of soils
This European Standard specifies the determination of Kjeldahl nitrogen according to the Kjeldahl procedure in sludge, treated biowaste and soil.
Nitrate and nitrite are not included.
Compounds with nitrogen bound in N-N, N-O linkages and some heterocycles (pyridines) are only partially determined.
The limit of detection (LOD) is usually 0,03 % nitrogen, and the limit of quantification (LOQ) is 0,1 % nitrogen (using 0,25 mol/l sulfuric acid for titration).
