DETERMINATION OF AMMONIA NITROGEN BY SEMI-AUTOMATED COLORIMETRY. 1.0 SCOPE AND APPLICATION. 2.0. 1.1. 1.2. 1.3 This method covers the determination of ammonia in drinking, ground, surface, and saline waters, domestic and industrial wastes. The applicable range is 0.01-2.0 mg/L NH as N. Higher concentrations can be. 3. determined by sample dilution.
Oct 1, 2019 · Ammonia nitrogen, consisting of un-ionized ammonia and ammonium, is a key parameter for studying the nitrogen cycle and indicating water quality. The measurement of these parameter concentrations is vital for the adequate monitoring of aquatic environments.
Ammoniacal Nitrogen (NH 3-N) and Suspended Solids (SS). High BOD can be attributed to untreated or partially treated sewage and discharges from agro-based industries and manufacturing industries. The main sources of NH 3-N were livestock farming and domestic sewage, while the sources for SS were mainly due
The source of ammoniacal nitrogen has been identified in this study such as the activity of agricultural development and rapid development. The reading of the concentration is high than the standard of NWQSM for Class IIB. The standard for concentration of ammoniacal nitrogen in water body is 0.3 mg/l. It is not good if the concentration of ...
Dec 12, 2020 · Ammonium ion of digested samples of food, soil, fertilizer and water was determined based on the reaction of the ammonium ion with formaldehyde, and then titrated with sodium hydroxide solution.
Aim To determine the ammonia nitrogen of the given sample of water. Principle Colorimetric method, using Nessler s reagent is sensitive to 20mg/L of ammonia N and may be used up to 5mg/L of ammonia N. Turbidity, colour and substances precipitated by hydroxyl ion interfere with the determination.
