Abstract

Przedmiotem wynalazku jest sposób spektrofotometrycznego oznaczania stezenia poli(chlorku diallilodimetyloamonowego) w roztworach wodnych, przydatny szczególnie do kontroli procesów uzdatniania wody, w którym do spektrofotomerycznego oznaczania stezen poli(chlorku dallilodimetyloamonowego) w roztworach wodnych stosuje sie odczynnik Bradford (kwasny wodno-alkoholowy roztwór Blekitu Brylantowego Coomassie G-250). Roztwory wzorcowe do wyznaczenia krzywej kalibracyjnej przygotowuje sie poprzez zmieszanie w kolbce miarowej próbki analitu z porcja odczynnika Bradford i uzupelnieniu woda destylowana. Pomiary absorbancji mozna prowadzic w zakresie dlugosci fali 570-630 nm wobec wody destylowanej. Zaleznosci absorbancji od stezenia PDDA w roztworze mozna opisac wielomianem trzeciego stopnia. The subject of the invention is a method for spectrophotometric determination of the concentration of poly (diallyldimethylammonium chloride) in aqueous solutions, particularly useful for controlling water treatment processes in which Bradford reagent (acid water-alcohol solution of Blekl Brilliant Brilliant Brilliant Brilliant Blue) Coomassie G-250). Standard solutions for the determination of the calibration curve are prepared by mixing an analyte sample in a measuring flask with a portion of Bradford reagent and making up with distilled water. Absorbance measurements can be made in the 570-630 nm wavelength range against distilled water. The dependence of absorbance on the PDDA concentration in solution can be described by a third degree polynomial.
