Abstract
U ovom radu je ispitivana koncentracija nikla u uzorcima tla voltametrijskom metodom na elektrodi od staklastog ugljika modificiranom slojem žive. Analizirana su tri uzorka tla: komercijalno dostupni organski mineralni supstrat (COMPO SANA® ) i dva uzorka tla uzeta u Botaničkom vrtu Prirodoslovno- matematičkog fakulteta Sveučilišta u Splitu. Za određivanje nikla primijenjena je metoda katodne adsorpcijske voltametrije s pravokutnim izmjeničnim signalom pobude (SWAdCSV), pri čemu se koristio sloj žive na elektrodi od staklastog ugljika. Ova metoda uključuje kompleksaciju nikla s dimetilglioksimom i adsorpciju nastalog kompleksa na sloju žive. Koncentracije nikla u uzorcima izračunate su korištenjem metode standardnog dodatka. Koncentracija nikla u tlu iz botaničkog vrta (c(Ni 2+ ) Tlo1 = 106,97 mg/kg; c(Ni 2+ ) Tlo2 = 179,11 mg/kg) odgovara rasponu koncentracija pronađenom u literaturi (c(Ni 2+ )= 5 - 500 mg/kg), te je viša od koncentracije u organskom mineralnom supstratu (c(Ni 2+ ) Tlo3 = 61,45 mg/kg). Koncentracija u uzorku Tla 3 je viša od navedene na deklaraciji (c(Ni 2+ )= 6,7 mg/kg).
Abstract (english)
In this paper concentracions of nickel in soil samples were determined by voltammetric method on mercury-film modified glassy carbon electrode. Three soil samples were analyzed: commercially available organic mineral substrate (COMPO SANA®) and two samples of soil taken from the Botanical Garden of the Faculty of Science, University of Split. For the determination of nickel, a method of Square-wave Adsorptive Cathodic Stripping Voltammetry (SWAdCSV) was used, using a mercury-film modified glassy carbon electrode. This method includes nickel complexation with dimethylglyoxime and adsorption of that complex on mercury film. The nickel concentrations in the samples were calculated using the standard addition method. The nickel concentracions in soil samples taken from Botanical Garden (c(Ni 2+ ) Soil1 = 106,97 mg/kg; c(Ni 2+ ) Soil2 = 179,11 mg/kg) corresponded to the concentracion range found in literature (c(Ni 2+ )= 5 - 500 mg/kg) and were higher than the concentracion in organic mineral substrate (c(Ni 2+ ) Soil3 = 61,45 mg/kg). Concentration in the sample of Soil 3 was higher than stated on the declaration (c(Ni 2+ )= 6,7 mg/kg).
