Abstract

Infracrvena spektroskopija proučava interakciju elektromagnetskog zračenja IR dijela spektra i materije. IR spektroskopija omogućava ispitivanje uzoraka na jednostavan, brz i nedestruktivan način. Može se primjeniti na plinovite, tekuće i krute uzorke.
Ovaj rad daje pregled spektara i identifikacije raznovrsnih ambalažnih materijala korištenih u svakodnevnom životu. Identifikacija se provodi na temelju položaja i intenziteta apsorpcijskih vrpci koje su specifične za određenu strukturnu skupinu. U ovome radu snimljeno je 44 različitih ambalažnih materijala, te su snimljenim vrpcama pripisane katakteristične skupine.
Identifikacija strukturnih skupina u uzorcima ambalažnih materijala analiziranih u ovome radu pokazuje da je većina ambalažnih materijala izrađena od polietilena, polistirena i poli(vinil-klorida).

Abstract (english)

Infrared spectroscopy studies the interaction between electromagnetic radiation of IR part of spectrum and matter. IR spectroscopy allows sample testing in a simple, fast and non-destructive manner. It can be applied on gaseous, liquid and solid samples.
This paper provides an overview of spectra and identification of various packaging materials used in everyday life. The identification is carried out based on the position and intensity of the absorption bands that are specific to a particular structural unit. In this paper 44 samples of various packaging materials were recorded. Characteristic groups were attributed to each recorded band.
Identification of structural groups of packaging materials studied in this paper showed that most packaging materials are made of polyethylene, polystyrene and poly (vinylchloride).
