The anionic, cationic and nonionic polyacrylamide samples, as well as four kinds of inorganic salt samples, including sodium sulfate, sodium chloride, sodium carbonate and ammonium sulfate, were respectively analyzed with Fourier transform infrared spectroscopy (FT-IR) to establish their standard reference infrared spectra, meanwhile the characteristic peaks are distinguished. At the same time, the polyacrylamide samples containing different concentration and different kinds of inorganic salts were respectively analyzed with FT-IR to establish their IR spectra. Then a method used for quality control of polyacrylamide products was established, which can be used to evaluate the purity of the products, determine the impurities and relevant contents preliminarily.
