Abstract
Przedmiotem zgłoszenia jest sposób spektrofotometrycznego oznaczania stężenia karagenu w roztworach wodnych, przydatny w przemyśle spożywczym, kosmetycznym, farmaceutycznym, w którym do spektrofotomerycznego oznaczania stężeń karagenu w roztworach wodnych stosuje się wodny roztwór barwnika New Methylene Blue N. Porcję analitu o znanej objętości miareczkuje się roztworem barwnika, rejestrując w sposób ciągły absorbancję mieszaniny roztworów przy długości fali z zakresu od 620 - 630 nm. Punktem końcowym miareczkowania jest osiągnięcie zadanej wartości absorbancji. Stężenie karagenu (C) odczytuje się z krzywej kalibracyjnej w postaci C=f(VNMB), gdzie VNMB - objętość barwnika w punkcie końcowym.The subject of the application is a method of spectrophotometric determination of carrageenan concentration in aqueous solutions, useful in the food, cosmetics, pharmaceutical industries, in which the spectrophotomeric determination of carrageenan concentration in aqueous solutions uses a New Methylene Blue N aqueous dye solution. A portion of the analyte of known volume is titrated with a dye solution , continuously recording the absorbance of the solution mixture at a wavelength range from 620 - 630 nm. The end point of titration is to reach the absorbance set point. The carrageenan (C) concentration is read from the calibration curve in the form C = f (VNMB), where VNMB - dye volume at the end point.
