Abstract

In this paper the results obtained for concentration of the trace elements in some coals from the Republic of Macedonia are given. It became possible to determine the dependence between some of them. The representative sample was analyzed for proximate analysis as well as for the trace elements. AES-ICP techniques were used in determination of the trace elements in the coal. Five samples of the coal were analyzed for the presence of Ba, Cr, Pb, Zn, Cu, Ni, Mo, V, Se, Ag and Co. The results show that the content is in a range about Ba (83-298), Cr (12-29), Zn (8-89), Cu(4.4-27), Pb (1.8-8.7), Ni (7.8-17.5), Co (1.9-9.7), Mo (0.4- 2.8), V (14-57), As (6.5-26), Se (1.7-7.0). The concentrations of all trace elements in these coals are unremarkably, falling well within the range of the World class coals. These data do not indicate any potential for economics by-product, technological problems or environmental or health concerns. Keywords: Trace elements, coals, AES-ICP.
