Abstract
Przedmiotem wynalazku jest sposób spektrofotometrycznego oznaczania stężenia poli(chlorku diallilodimetyloamonowego) w roztworach wodnych, przydatny do kontroli procesów uzdatniania wody oraz oczyszczania ścieków. Sposób charakteryzuje się tym, że stosuje się barwnik Acid Orange 7. Roztwory wzorcowe do wyznaczenia krzywej kalibracyjnej jak również roztwory badane przygotowuje się poprzez zmieszanie w kolbce miarowej próbki analitu z porcją barwnika i uzupełnieniu wodą destylowaną. Pomiary absorbancji można prowadzić w zakresie długości fali 450 - 500 nm wobec wody destylowanej. Zależność absorbancji od stężenia PDDA w roztworze można opisać równaniem linii prostej. Oznaczenie przeprowadza się w środowisku kwaśnym lub obojętnym, przy zasoleniu nie przekraczającym 25 mmoli NaCl/dm3.The subject of the invention is a method of spectrophotometric determination of the concentration of poly (diallyldimethylammonium chloride) in aqueous solutions, useful for controlling water treatment processes and wastewater treatment. The method is characterized in that the Acid Orange 7 dye is used. Standard solutions for determining the calibration curve as well as the test solutions are prepared by mixing in the measuring flask an analyte sample with a portion of the dye and supplementing with distilled water. Absorbance measurements can be carried out in the wavelength range 450-500 nm against distilled water. The dependence of absorbance on the PDDA concentration in solution can be described by a straight line equation. The determination is carried out in an acid or neutral medium, with a salinity not exceeding 25 mmol NaCl / dm3.
