Abstract
Przedmiotem zgłoszenia jest sposób spektrofotometrycznego oznaczania stężenia poli(chlorku diallilodimetyloamonowego) w roztworach wodnych, cechujący się dużą czułością. Ilościowe oznaczanie stężenia poli(chlorku diallilodimetyloamonowego) wykorzystuje się w kontroli procesów uzdatniania wody oraz oczyszczania ścieków. Do spektrofotomerycznego oznaczania stężeń poli(chlorku dallilodimetyloamonowego) w roztworach wodnych stosuje się wodny roztwór barwnika - czerni eriochromowej T. Porcję analitu o znanej objętości miareczkuje się roztworem barwnika w temperaturze pokojowej, rejestrując w sposób ciągły absorbancję mieszaniny roztworów przy długości fali z zakresu od 530 do 550 nm. Punkt końcowy miareczkowania odczytuje się z krzywej miareczkowania na podstawie położenia miejsca skokowego obniżenia absorbancji, a stężenie PDDA oblicza się z krzywej kalibracyjnej. Zachowanie proponowanych warunków pomiaru umożliwia oznaczenie stężeń PDDA w zakresie od 0,01 mmol meru / dm3 wzwyż. Metoda może być stosowana w roztworach o niskiej i średniej kwasowości (odczyn pH od 3 do 6,5) bez dodatkowej korekcji odczynu.The subject of the application is a method of spectrophotometric determination of the concentration of poly (diallyldimethylammonium chloride) in aqueous solutions, characterized by high sensitivity. Quantitative determination of poly (diallyldimethylammonium chloride) is used to control water and wastewater treatment processes. For spectrophotomeric determination of poly (dallyl dimethylammonium chloride) concentrations in aqueous solutions, an aqueous dye solution is used - eriochrome black T. A portion of the analyte of known volume is titrated with a dye solution at room temperature, continuously recording the absorption of the solution mixture at a wavelength in the range from 530 to 550 nm. The titration endpoint is read from the titration curve based on the location of the abrupt absorbance decrease, and the PDDA concentration is calculated from the calibration curve. Compliance with the proposed measurement conditions enables the determination of PDDA concentrations in the range of 0.01 mmol meru / dm3 upwards. The method can be used in low and medium acidity solutions (pH 3 to 6.5) without additional pH correction.
