Popis: The chromaticity characteristics were studied for the product of the reaction of Nessler’s reagent with ammonium ions and for solutions of molecular iodine. These characteristics were used for the determination of the concentration variation step in the construction of the calibration plot in test methods. It was demonstrated that chromaticity measurements can be used for improving the sensitivity of the determination, and iodine solutions can be used in test methods for the construction of the scale simulating NH2Hg2I3.
