Abstract
Inventia se refera la o metoda de determinare a continutului de substante organice din apele de alimentare utilizînd spectrofotometria în UV-VIS. Metoda conform inventiei prevede înregistrarea spectrului electronic al apei de analizat ce corespunzatoare maximelor de absorbtie prepararea a 8....10 amestecuri din apa de analizat cu apa distilata în raport de diluare cunoscut determinarea indicelui de oxidabilitate la permanganat de potasiu si ridicarea spectrelor electronice pentru toate amestecurile realizate trasarea curbei de etalonare care coreleaza valorile exnctiei la primul maxim de absorbtie functie de continutul organic la probele preparate determinarea pe aceasta curba a continutului organic al unei probe necunoscute din apa de analizat printr-o simpla cirtire a extinctiei la lungimea de unda analitica aleasa în acelasi conditii de masurare.The invention relates to a method of determining the content of organic substances in feed water using spectrophotometry in UV-VIS. The method according to the invention provides for the recording of the electronic spectrum of the water to be analyzed corresponding to the absorption maxima the preparation of 8 ... 10 mixtures of the water to be analyzed with distilled water in known dilution ratio determination of the oxidation index to potassium permanganate and the raising of the electronic spectra for all mixtures made plot the calibration curve that correlates the extinction values to the first maximal absorption depending on the organic content of the prepared samples determination on this curve of the organic content of an unknown sample from the water to be analyzed by a simple quenching of the extinction to the analytical wavelength chosen under the same measurement conditions.
