Abstract
A method for rapid determination of antioxidant Irganox 1076 in polyolefin by Fourier transform infrared spectroscopy was established. By comparing the infrared spectra of Irganox 1076 and polypropylene, the absorption peak of Irganox 1076 at 1738 cm-1 was selected as the detection peak. Within the concentration range involved, the standard curve equation of Irganox 1076 in PP is y = 0.00593 + 0.12681x, and the linear regression coefficient is 0.98742. The standard curve was used to determine the content of Irganox 1076 in the actual sample, and the maximum relative error was 6.85%. The method is accurate, rapid and sensitive, which can be used for on-line monitoring of processing and using polyolefin products.
