Abstract

Przedmiotem wynalazku jest sposób fluorymetrycznego oznaczania stężenia poli(chlorku diallilodimetyloamonowego) w roztworach wodnych, w którym do oznaczania stężeń polichlorku dallilodimetyloamonowego) stosuje się wodne roztwory fluoresceiny lub 2,7-dichlorofluoresceiny. Roztwory wzorcowe do wyznaczenia krzywej kalibracyjnej oraz roztwory badane przygotowuje się poprzez zmieszanie w probówkach określonej ilości roztworu wskaźnika z dawką roztworu PDDA, odpowiednio o znanym zmiennym stężeniu lub o nieznanym stężeniu. Pomiary intensywności fluorescencji prowadzi się przy długości fali 494 nm (dla fluoresceiny) lub 500 nm (dla 2,7-dichlorofluoresceiny) wobec tzw. ślepej próby.The subject of the invention is a method of fluorimetric determination of the concentration of poly (diallyldimethylammonium chloride) in aqueous solutions, in which aqueous solutions of fluorescein or 2,7-dichlorofluorescein are used to determine the concentrations of dallyl dimethylammonium chloride. Standard solutions for the determination of the calibration curve and test solutions are prepared by mixing in a test tube a specific amount of indicator solution with a dose of PDDA solution of known variable concentration or unknown concentration, respectively. Measurements of fluorescence intensity are carried out at 494 nm (for fluorescein) or 500 nm (for 2,7-dichlorofluorescein) against so-called blank.
