How can you identify zeolite from FTIR?
This page summarizes the recurring FTIR evidence reported for zeolite, 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.

Schnelle Antwort
zeolite 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.
Peak-Interpretation
Mögliche Materialien / Gruppen
| Funktionelle Gruppe | Beweis |
|---|---|
| Hydroxyl (O-H) | 16 |
| Alkyl C-H | 10 |
| Siloxane (Si-O-Si) | 7 |
| Silicon-oxygen (Si-O) | 7 |
| Metal oxygen | 7 |
| N h | 5 |
| Silicon (Si) | 5 |
| Adsorbed carbon monoxide | 5 |
Spektrumslogik
The logic here is evidence aggregation: repeated literature mentions of zeolite, 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.
Praktische Anwendung
Diese Seite ist für die Polymeridentifikation, die Qualitätskontrolle eingehender Materialien, die Analyse unbekannter Kunststoffe, die Überprüfung des Recyclinganteils und die literaturgestützte Interpretation von Referenzspektren konzipiert.
Häufige Fehler
- Zu frühes Erkennen einer Materialübereinstimmung, weil ein bekannter Peak vorhanden ist.
- Ignorieren von Probenvorbereitung, Füllstoffen, Oxidation, Wasser oder Additiven, die das offensichtliche Muster verändern können.
- Verwendung von Literaturbelegen, ohne zu prüfen, ob Ihr eigener Probenahmemodus und Ihre Spektrenqualität vergleichbar sind.
Beratung zur Verifizierung
Verwenden Sie DSC, GC-MS oder TGA, um die Materialhypothese zu validieren, wenn das Peak-Muster mehrdeutig oder gemischt ist.
