Quantitative Determination of Tetraacetylethylenediamine in Laundry Powder by FTIR Spectrometry Using Partial Least Squares Algorithm

Abstract

Abstract Attenuated total reflectance Fourier transform infrared spectrometry was applied for determination of tetraacetylethylenediamine (TAED) in commercial laundry powder samples. Investigating different spectral regions, 1724–1670 cm−1 was selected as the best region. Spectroscopic data were compared with gas chromatography results, demonstrating reliability of the proposed method, higher accuracy and precision. Standard error of estimation (SEE), standard error of prediction (SEP), correlation coefficient (R2) and root mean square error of prediction (RMSEP) was 0.022, 0.031, 0.998 and 0.138 in the selected spectral region, respectively.
