Za procenu kvaliteta cumura kao goriva (potencijalni materijal sa raznovrsnom primenom), izvršeno je određivanje elementarnog sastava (sadržaj C , H , N, S u procentima), kao i mikro analiza devet uzoraka ćumura. Ćumur sadrži razlicite koncentracije elemenata u tragovima. Nakon kisele digestije, određivanje mikroelemenata (As, Cd, Cu, Cd, Pb, Mn, Ni, Mn, Mo, Sb, Sn, B, Be, Ba i Zn) u ispitivan im uzorcima je izvršeno primen om ICP-MS instrumentalne tehnike. Dobijeni rezultati su pokazali da devet ispitivanih uzoraka ćumura, sadrži mikroelemente u tragovima, u prihvatljivom opsegu koncentracija, sa ukupnim opsegom od 0,9 mg/kg (Sb) do 59,45 mg/kg (Mn). Since charcoal is traditionally produced from different types o f wood, there is a growing need to control the quality ofproduced charcoal (activated carbon). To assess the quality o f charcoal as a fuel, the elemental composition (content C, H, N, S) was determined, as well as the micro-analysis o f nine charcoal samples. Charcoal contains different concentrations o f trace elements. After acid digestion, determination o f micro elements (As, Cd, Cu, Cd, Pb, Mn, Ni, Mn, Mo, Sb, Sn, B, Be, Ba and Zn) in the tested samples was performed using the ICP- MS instrumental techniques. The obtained results showed that the nine tested samples o f charcoal contained the micro elements in the acceptable range o f concentrations, with a total range from 0.9 mg/kg (Sb) up to 59.45 mg/kg (Mn). application/pdf 418481 bytes
