Method for quantitative determination of poly(diallyldimethylammonium chloride) in water solutions with medium and high concentrations

摘要

the object of the application is a spectrophotometric determination of the concentration of poly (diallilodimetyloamonowego chloride) in aqueous solutions with a large measurement range. quantitative determination of the concentration of poly (diallilodimetyloamonowego) is used in the control of wastewater treatment.to spektrofotomerycznego determine concentrations of poly (dallilodimetyloamonowego chloride) in aqueous solutions using aqueous solution of an acidic dye - orange ii. a portion of the analyte of known volume miareczkuje solution dye at room temperature; the continuous absorbance mixture solutions at wavelength range 475 to 495 nm.the end point of titration is read from the titration curve based on the selected value of absorbance and the concentration pdda is calculated from the calibration curve. behavior proposed measurement conditions permits the determination of pdda range from 0.02 mmol meru / dm3 upwards.the method can be used in solutions of low and medium acidity and inert solutions (ph from 3 to 7) without additional correction reaction, as well as in solutions with low salinity.
