Abstract EN
Analytical methods based on spectroscopic techniques were developed and validated for the determination of diethyl phthalate (DEP) and polyhexamethylene guanidine (PHMG), which may occur in unrecorded alcohol.
Analysis for PHMG was based on UV-VIS spectrophotometry after derivatization with Eosin Y and 1H NMR spectroscopy of the DMSO extract.
Analysis of DEP was performed with direct UV-VIS and 1H NMR methods.
Multivariate curve resolution and spectra computation methods were used to confirm the presence of PHMG and DEP in the investigated beverages.
Of 22 analysed alcohol samples, two contained DEP or PHMG.
1H NMR analysis also revealed the presence of signals of hawthorn extract in three medicinal alcohols used as surrogate alcohol.
The simple and cheap UV-VIS methods can be used for rapid screening of surrogate alcohol samples for impurities, while 1H NMR is recommended for specific confirmatory analysis if required.
