WebMar 11, 2024 · All spectra were acquired using the Attenuated Total Reflectance (ATR) mode with a FTIR spectrometer (spectrum 2000, Perkin Elmer, Waltham, MA, USA). Spectra were acquired in the scan range between 4000.00–530.00 cm −1 , with a resolution of 4.00 cm −1 and a total of 8 scans for each sample that were averaged to eliminate background noise. http://www.arpnjournals.org/jeas/research_papers/rp_2024/jeas_0323_9127.pdf
