Method for quantitative determination of anionic polymers concentration in water solutions with increased ionic strength value

摘要

the object of the application is the quantitative determination of the concentration of anionic polymers as in aqueous solutions of high ionic strength values, useful in industrial and environmental analysis. in the way to spektrofotomerycznego determine concentrations of anionic polymers in aqueous solutions containing nacl apply aqueous dye - methylene blue.solution the analyte ion strength leads to a certain value, and then a portion of the analyte with a known volume miareczkuje dye solution; the continuous absorbance mixture solutions at wavelength range 660 to 670 nm. endpoint titration is to achieve a given value of absorbance.the concentration of polymer (c) is read from the calibration curve in the form of c = f (vbm) (where vbm - volume of dye at the end point).
