Testování metody stanovení dusi?nan? s vyu?itím p?enosného fotometrického analyzátoru

摘要

In this work, a method to determine NO_(3)~(–) using portable analyzer Photometer PF-12 (Macherey-Nagel, Germany) for analysis of model solutions, and drinking as well as natural water was tested. The obtained results have been compared with those achieved by flow injection analysis and by spectrophotometrically followed simultaneous neutralizing microtitration.
