Abstract
Spektrofotometrija je analitička tehnika koja se upotrebljava za kvalitativnu i kvantitativnu analizu. Absorpcijski spektri otopina sastoje se od neprekinutih vrpca u vidljivom i ultraljubičastom spektralnom području. Spektrofotometrijska Folin-Coiucalteu metoda primjenjuje se za određivanje ukupnih polifenola. Derivat benzojeve kiseline je p-hidroksibenzojeva kiselina koja se nalazi u proizvodima prehrambene industrije (džemovi, želei, obrađena riba, smrznuti mliječni proizvodi, umaci, deserti i bezalkoholna pića). Stoga je cilj ovog završnog rada snimiti spektre p-hidroksibenzojeve kiseline različitih koncentracija u ultraljubičastom i vidljivom području i primijeniti metodu određivanja ukupnih polifenola na različite koncentracije p-hidroksibenzojeve kiseline.
Abstract (english)
Spectrophotometry is an analytical technique used for qualitative and quantitative analysis. The absorption spectrum of the solution consists of continuous bands in the visible and ultraviolet spectral range. Spectrophotometric Folin-Ciocalteu method is used to determine total polyphenols. The benzoic acid derivative is p-hydroxybenzoic acid found in food industry products (jams, yoghurts, processed fish, frozen dairy products, sauces, desserts and non-alcoholic beverages). The aim of this work is to record p-hydroxybenzoic acid spectra of different concentrations in the ultraviolet and visible region and apply a method for determining total polyphenols at different concentrations of p-hydroxybenzoic acid.
