Method for determination of trace amounts of poly (diallyldimethylammonium chloride) in water solutions

摘要

the subject invention is a spectrophotometric determination of the concentration of poly (diallilodimetyloamonowego chloride) in aqueous solution with high sensitivity and useful for the control of water treatment and sewage treatment.way is to use dye brilliant blue coomassie g - 250 (bbc), identified using cas number: 6104 - 58 - 1, the model for all the items concerned c47h48n3o7s2na2 and molar mass m = 877 g / mol, for spectrophotometric determination of the concentrations of poly (diallilodimetyloamonowego chloride) in solutions wodnyc h.the basis of a sample analyte containing solution titration pdda bbc of specified concentration while measuring the absorbance at a wavelength of from the system from 575 to 588 nm (preferably 580 nm). the end point of titration is determined by the position of the ankle lower absorbance plotted according a = f (vbarwnika).
