WebIntroduction. Fourier transform infrared (FTIR) spectroscopy is a form of vibrational spectroscopy that is useful in the study of a variety of soil chemical processes. In the mid-infrared (mid-IR) range, vibrations arise from many environmentally important molecules such as organic acids, soil organic matter, mineral phases, and oxyanions. WebApr 13, 2024 · To analyze the effect of polyol on polyurethane (PU)-modified asphalt, three different soft segments of polyurethane were synthesized, and we utilized the reaction of MDI (diphenylmethane diisocyanate) with PU650, PU1000, and PU1400. With respect to molecular weight, the effect of polyol on the performance of modified asphalt was …
WebNov 14, 2024 · In addition, the peak of the C C bond newly formed by the hydroxyl–yne click reaction appeared from 120 ppm to 140 ppm. The peak at around 190 ppm was attributed to C O in the CPPKs. These results further demonstrated the conclusion drawn from the FTIR spectra that the CPPKs were successfully prepared by the hydroxyl–yne click reaction.
WebFTIR stands for “Fourier transform infrared” and it is the most common form of infrared spectroscopy. All infrared spectroscopies act on the principle that when infrared (IR) radiation passes through a sample, some of the radiation is absorbed. The radiation that passes through the sample is recorded.
