Method for determining the concentration of poly (diallyldimethylammonium chloride) in aqueous solutions

摘要

method of determining the concentration of poly (diallilodimetyloamonowego chloride) in aqueous solutions is useful particularly to control the processes of water treatment, and is characterized by the fact that spektrofotomerycznego to determine concentrations of this relationship applies aqueous dye - black s seminar 10ob.both the reference solutions to designate the calibration curve and the sample for testing is prepared in sealed tubes by mixing a portion of the analyte with the appropriate dose of dye solution. the tube is set aside for 24 hours, and then in the same tubes are measured at a wavelength of 620 nm absorbance against distilled water.
