Objective - development of sensory systems the determination of nitrate in water. Methods of study - three-wave photometry , statistics. Key Results - a portable spectrophotometer designed for the determination of nitrate in water according to the absorption of light at three wavelengths in the interval ( 220-260 ) nm. The light source is a deuterium lamp , spectral splitting grating dispersion is carried out and recorded by the photodiode line . Received satisfactory metrological characteristics of the instrument on the basis of the determination of nitrate in model solutions and in drinking water . The recommendations on the preliminary oxidation treatment of water containing significant amounts of humic substances and other contaminants . Scientific novelty - the application line photodiode as a detector in the instrument. Practical value - rapid monitoring of nitrates in aqueous media. Scope - environmental protection.5481 Product Description popup.authors Бенюк Михайло Володимирович Демуцька Людмила Миколаївна Калініченко Іван Омелянович Орєхова Олена Олександрівна Таранов Віктор Васильович popup.nrat_date 2020-04-02 Close
