Determination of active ingredients in commercial insecticides using spectral characteristics of Fourier transform infrared spectroscopy (FTIR)

Abstract

Pesticides have become a basic necessity for yield development. This might be credited to the quickly expanding population, which has presented weight on the food creation industry.Fourier Transform Infra-red Spectroscopy utilizes sample with less course of action, less time consuming, simple, fast, non-destructive and environmental friendly infrared-based method. It makes use of Smart iTR window and pellets use on omnic transmission window. In FTIR the peaks formed for the representative sample are from 800 cm-1 to 4000 cm-1 of wavenumbers against the % transmittance. The FTIR spectra obtained for pesticide formulations were on par with the NIST (National Institute of Standards and Technology) spectra library. Comparing the commercial-grade spectra with the Spectrabase, NIST library and Bio-rad software showed the peak ranges for different functional groups of the compound and can be examined with KnowItAll software’s ProcessItIR and AnalyseItIR. We can obtain the active principle of the peak, peak intensities. This method can be viewed as genuine choices to long and tedious chromatographic strategies as a rule suggested for quality control of commercially accessible pesticide formulations and check for adultered formulations that harm agricultural produce.

“…Briefly, potassium bromide crystals were ground to powder and pressed into tablets after thorough grinding and mixing in the ratio of 1:100 (sample: potassium bromide). The spectra were scanned using an FTIR spectrometer, and the spectra were recorded in the range of 4000-500 cm -1 , with a resolution of 4 cm -1 and 32 scans in the transmission mode (Szymanśki, 2017;Tafintseva et al, 2019;Lin et al, 2020;Mohamed and Janaki, 2021).…”

“…The FTIR spectra were automatically baseline corrected and smoothened using the Omnic 8.2 software, and the absorption peaks were regionally integrated (Lin et al, 2020;Mohamed and Janaki, 2021). The signal intensity of each absorption peak was obtained by calculating the percentage of each absorption peak area to the total peak area.…”
