The Water Analysis Handbook (WAH) is the result of more than 85 years of research and method development. That post addressed the need to run the full gamut of nitrogen tests which include TKN, ammonia, nitrate, and nitrite, the sum of which equate to the total nitrogen concentration as illustrated in Figure 1. 3. In this post I want to focus on what is required to run these nitrogen tests by detailing the equipment and reagents I use in the field. The TKN test measures the concentration in a range from 0 to 16 mg/L N. I have never tested an influent wastewater sample with a TKN concentration 16 mg/L (see Table 1). The color chart has matches at -5-10-20-50-100ppm.

After reading test results, leave the sample cell (unspiked sample) in the instrument. Bacteria in your gut and in your cells create ammonia when your body breaks down protein. /[u=@ !HY? I use Hach's DR 1900 spectrophotometer pictured in Figure 7. But industrial wastewater plants can have highly variable influent COD concentrations so you need to make sure you have a good understanding of the influent organic loading. , . In general, direct manual determination of low concen-trations of ammonia is conned to drinking waters, clean surface But several other things can cause higher ammonia levels, like: A low level of ammonia could be caused by very high blood pressure that comes on quickly and suddenly. At one time, I had spiked Hach's nitrate standard with salt and recorded absorption to find multiplier.
