Аннотация: A less expensive and simpler method than the existing one for determination of the degree of oxidation of polyaniline that includes reduction with excess SnCl2 in a 50% solution of sulfuric acid and subsequent reverse titration of unreacted SnCl2 with a solution of K2Cr2O7 with a molar concentration of the equivalent of 0.1 mole/dmПоказать полностью(3) in the presence of diphenylamine as the indicator is described. The standard deviation does not exceed 0.22%.
