20.500.12556/DKUM-38659 DOLOČEVANJE KADMIJA IN SVINCA V ZEMLJI Z ELEKTROTERMIČNO ATOMSKO ABSORPCIJSKO SPEKTROMETRIJO DETERMINATION OF CADMIUM AND LEAD IN SOIL WITH GRAPHITE FURNANCE ATOMIC ABSORPTION SPECTROMETRY Namen diplomskega dela je bil validacija analizne metode za določanje vsebnosti kadmija in svinca v zemlji z elektrotermično atomsko absorpcijsko spektrometrijo (ETAAS). Kadmij in svinec smo določali po standardni metodi ISO 11047:1998 (Kakovost tal - Določevanje kadmija, kroma, kobalta, bakra, svinca, mangana, niklja in cinka - Metoda plamenske in elektrotermične atomske absorpcijske spektrometrije). Izvedena je bila validacija anlizne metode, pri kateri smo določili in preverili območje določanja, premosorazmernost signala in koncentracije v območju določanja, natančnost in točnost določitev ter časovno stabilnost preskusnih vzorcev. Ocenili smo merilno negotovost. The purpose of this diploma thesis was the validation of the analytical method for the determination of cadmium and lead in soil with electrothermal atomic absorption spectrometry (ETAAS). Cadmium and lead were determined according to standard methods ISO 11047:1998 (Soil quality – Determination of cadmium, chromium, cobalt, copper, lead, manganese, nickel and zinc – Flame and electrothermal atomic absorption spectrometric methods). The validation of the analytical method was performed. Working range, Limit of detection, limit of quantitation, linearity, accuracy, precision, temporal stability of the prepared samples were determined. Measurement uncertainties were estimated. kadmij svinec ETAAS elektrotermična atomska absorpcijska spektrometrija validacija cadmium lead ETAAS electrothermal atomic absorption spectrometry validation true true false [U.
