Аннотация: A simple and rapid procedure for the potentiometric determination of polyethylene glycol with a molecular mass of 20000 (PEG-20000) was proposed. The procedure: is based on the empirically found stoichiometry of the reaction of PEG-20000 precipitation with iodine. Titration was performed to a constant potential of the I-3/3I(-) redПоказать полностьюox couple measured with a platinum electrode. The relative standard deviation for PEG-20000 concentrations from 6.0 to 19.9 g/L was less than or equal to 5%.
