Abstract

Przedmiotem wynalazku jest sposób spektrofotometrycznego oznaczania stężenia poli(chlorku diallilodimetyloamonowego) w roztworach wodnych, cechujący się dużą czułością i przydatny do kontroli procesów uzdatniania wody oraz oczyszczania ścieków. Sposób polega na zastosowaniu barwnika Błękit Brylantowy Coomassie G-250 (BBC), identyfikowanego numerem CAS: 6104-58-1, o wzorze sumarycznym C47H48N3O7S2Na2 oraz masie molowej M=877 g/mol, do spektrofotometrycznego oznaczania stężeń Poli(chlorku diallilodimetyloamonowego) w roztworach wodnych. Podstawę oznaczenia stanowi miareczkowanie próbki analitu zawierającego PDDA roztworem BBC o określonym stężeniu z jednoczesnym pomiarem absorbancji układu przy długości fali z zakresu od 575 do 588 nm (optymalnie 580 nm). Punkt końcowy miareczkowania wyznacza się poprzez określenie położenia punktu skokowego obniżenia absorbancji na wykresie zależności A=f(Vbarwnika).The subject of the invention is a method of spectrophotometric determination of the concentration of poly (diallyldimethylammonium chloride) in aqueous solutions, characterized by high sensitivity and useful for controlling water treatment processes and wastewater treatment. The method involves the use of Brilliant Blue Coomassie G-250 (BBC) dye, identified by CAS number: 6104-58-1, with the sum formula C47H48N3O7S2Na2 and molar mass M = 877 g / mol, for spectrophotometric determination of Poly (diallyl dimethylammonium chloride) concentrations water. The basis of the determination is the titration of the PDDA analyte sample with a BBC solution of a certain concentration with simultaneous measurement of the system absorbance at the wavelength range from 575 to 588 nm (optimally 580 nm). The titration end point is determined by determining the position of the absorbance reduction step on the plot of the relationship A = f (V dye).
