How can you identify curcumin from FTIR?
This page summarizes the recurring FTIR evidence reported for curcumin, including the most frequent peaks, supporting functional groups, and literature-backed interpretation patterns. It is a structured evidence page, not a claim of automatic single-spectrum certainty.

Snel antwoord
curcumin is usually reported with a recurring pattern of peaks and functional-group evidence. The most useful approach is to cross-check at least two characteristic peaks before treating it as a match, then verify whether the full spectrum still fits the same material family.
Piekinterpretatie
Mogelijke materialen / groepen
| Functionele groep | Bewijs |
|---|---|
| Amide | 16 |
| Alkyl C-H | 14 |
| Methacrylate | 13 |
| Acetate | 13 |
| Hydroxyl (O-H) | 13 |
| C-O single bond | 9 |
| Carbonyl (C=O) | 9 |
| Methoxy (OCH3) | 8 |
Spectrumlogica
The logic here is evidence aggregation: repeated literature mentions of curcumin, repeated peak positions, and repeated functional-group associations. A strong material hypothesis should still be supported by multiple peaks that agree with each other, not by one headline band alone.
Gebruik in de praktijk
Deze pagina is ontworpen voor polymeeridentificatie, kwaliteitscontrole van inkomend materiaal, analyse van onbekende kunststoffen, beoordeling van gerecycled materiaal en literatuurondersteunde interpretatie van referentiespectra.
Veelgemaakte fouten
- Te vroeg een materiaalovereenkomst vaststellen omdat één bekende piek aanwezig is.
- Monstervoorbereiding, vulstoffen, oxidatie, water of additieven die het patroon kunnen veranderen negeren.
- Literatuurbewijs gebruiken zonder te controleren of uw eigen monsternamemethode en spectrumbenadering vergelijkbaar zijn.
Advies voor verificatie
Gebruik DSC, GC-MS of TGA om de materiaalhypothese te valideren wanneer het piekpatroon dubbelzinnig of gemengd is.
