Hypothesis
The study aims to develop a methodology for determining zinc in Brazilian sugar cane spirit using solid-phase extraction with Moringa oleifera husks.
Conclusion
The proposed method is a low-cost and effective way to determine zinc levels in Brazilian cachaça without requiring sample pretreatment.
Supporting Evidence
- The method achieved a limit of detection for zinc at 1.9 μg L−1.
- The analytical curve was linear from 2 to 50 μg L−1 with a correlation coefficient of 0.9996.
- Recovery tests showed results ranging from 83% to 100% for spiked samples.
Takeaway
This study found a simple way to check how much zinc is in Brazilian sugar cane spirit using a natural material, making it easier and cheaper for producers.
Methodology
The method involves solid-phase extraction using activated carbon from Moringa oleifera husks and detection by flame atomic absorption spectrometry (FAAS).
Limitations
The method may not be applicable to all types of alcoholic beverages and relies on specific conditions for optimal results.
