Hypothesis
Can UV-VIS and NMR spectroscopy effectively identify diethyl phthalate (DEP) and polyhexamethylene guanidine (PHMG) in surrogate alcohols?
Conclusion
The study successfully developed and validated UV-VIS and NMR methods for detecting DEP and PHMG in alcoholic beverages.
Supporting Evidence
- Two out of 22 analyzed alcohol samples contained DEP or PHMG.
- 1H NMR analysis confirmed the presence of DEP and PHMG in the samples.
- UV-VIS methods were found to be simple and cost-effective for screening.
Takeaway
Researchers found ways to quickly check if harmful chemicals are in some alcoholic drinks, which can help keep people safe.
Methodology
The study used UV-VIS and 1H NMR spectroscopy to analyze 22 alcohol samples for the presence of DEP and PHMG.
Limitations
The lack of commercial availability of pure PHMG standards limited the quantification methods.
Participant Demographics
Samples included commercial vodkas, medicinal alcohol, homemade samogon, and surrogate alcohol from three cities in Russia.
