Abstract

U ovom radu je provedena validacija dvije spektrometrijske metode za odreĎivanje niklaoptičke emisijske spektrometrije s induktivno spregnutom plazmom (ICP-AES) i atomske
apsorpcijske spektrometrije (AAS). Tijekom validacijskog postupka odreĎivana je: točnost,
preciznost, linearnost, radno područje, specifičnost, selektivnost, granica detekcije, granica
kvantifikacije i reproducibilnost. Dobiveni podaci ukazuju na to da su obje ispitivane metode
točne, precizne, specifične, selektivne i reproducibilne. Ispitivanja su pokazala da metoda
atomske apsorpcijske spektrometrije nema zadovoljavajuću linearnost. Obje ispitivane metode
mogu se koristiti za odreĎivanje niskih koncentracija nikla budući da im je granica detekcije
0,7513 µg/L odnosno 0,7947 µg/L.

Abstract (english)

In this graduation thesis, two spectrometric methods for the determination of nickel -inductively coupled plasma optical emission spectrometry (ICP - AES) and atomic absorption
spectrometry (AAS) were validated. During the validation process, the accuracy, precision,
linearity, working area, specificity, selectivity, detection limit, quantification limit and
reproducibility were determined. The obtained data indicate that both methods were accurate,
precise, specific, selective and reproducible. Tests have shown that the atomic absorption
spectrometry method does not have satisfactory linearity. Both test methods can be used to
determine low nickel concentrations as their detection limits are 0.7513 μg/L and 0.7947
μg/L.
