WebOct 1, 2024 · Phansi et al. [17] reported a microfluidic paper-based analytical device (μPAD) combined with Nessler's reagent for the direct determination of ammonium concentration in wastewater and fertilizers. In this method, the color image was captured by the camera, and the color intensities were analyzed for ammonia quantification using the Image-J program.

Determination of NH4+ in Environmental Water with Interfering ... - Hindawi
Named after Julius Neßler (Nessler), an alkaline solution of K2HgI4 is called Nessler's reagent. This pale solution becomes deeper yellow in the presence of ammonia. At higher concentrations, a brown precipitate may form. The sensitivity as a spot test is about 0.3 μg NH3 in 2 μL. NH4 + 2 [HgI4] + 4 OH → + 7 I + 3 H2O The formula for the brown precipitate, a derivative of Millon's base, is given as 3HgO·Hg(NH3)2I… WebAbstract. The method for determination of ammonia in the air that has been used so far, based on the reaction with Nessler reagent, is outdated. In this method the final colour solutions are not non-ideal solution (there occurs turbidity), which may result in smaller accuracy of determination. Besides this method is not sufficiently specific. long random facts
