AB  - The objective of this study was to investigate corncob as biosorbent for heavy metals removal from aqueous solutions. All biosorption experiments were performed in batch system. The biosorbent were caracterized by thermal analysis (DTA/TGA), Scanning Electron Microscopy and Energy Disperzive X-Ray analysis (SEM-EDX) and Fourier Transform Infrared Spectroscopy (FTIR) analysis. FTIR analysis of corn cob before and after Pb2+, Cu2+ and Zn2+ removal from aqueous solutions showed that ion exchange and chemisorption were involved in biosorption process of metal ions on to corn cob. Experimental data were fitted by Langmuir and Freundlich isotherm models. Maximum adsorption capacity of corn cob for Pb2+, Cu2+ and Zn2+ were 5,59; 2,62 i 1,23 mg/g, respectively. Desorption study showed that metal adsorbed corn cob can be effectively regenerated by HNO3 solution. Results from this study indicated that corn cob can be used as potential biosorbent for Pb2+, Cu2+ and Zn2+ removal from aqueous solutions.
AB  - Cilj ovog rada je ispitivanje mogućnosti upotrebe oklaska kukuruza za uklanjanje teških metala iz vodenih rastvora. Svi biosorpcioni eksperimenti izvođeni su u šaržnom sistemu. Karakterizacija biosorbenta izvršena je termijskom analizom (DTA/TGA), metodom skenirajuće elektronske mikro-skopije i energijsko-disperzivne rendgenske analize (SEM-EDX) i infracrvenom spektroskopijom sa Furijeovom transformacijom (FTIR). Na osnovu FTIR analize oklaska kukuruza pre i nakon uklanjanja Pb2+, Cu2+ i Zn2+ jona, ustanovljeno je da jonska izmena i hemisorpcija učestvuju u procesu biosorpcije jona metala na oklasku kukuruza. Eksperimentalni rezultati obrađeni su Lengmirovim i Frojndlihovim modelom izotermi. Maksimalni adsorpcioni kapacitet oklaska kukuruza za Pb2+, Cu2+ i Zn2+ iznosi 5,59; 2,62 i 1,23 mg/g, respektivno. Nakon ispitivanja procesa desorpcije zaključeno je da se adsorbovani joni metala na oklasku kukuruza efikasno i lako mogu ukloniti rastvorom HNO3. Rezultati ovog istraživanja ukazuju da se oklasak kukuruza može primeniti kao potencijalni biosorbent za uklanjanje Pb2+, Cu2+ i Zn2+ jona iz vodenih rastvora.

AB  - Boka Kotorska Bay is on the UNESCO's World Heritage List. There are no published papers re-lated to the surface sediment pollution of the Bay. For the first time, elements were measured in surface sediments at nine locations in the Bay by the energy dispersive X-ray fluorescence spectrometry (ED-XRF) technique. Si, Fe, Ca, K, Ti, Mn, P, Ba, Cr, Sr, Zn, Rb, Ni, Cu, Pb, As, Sn, Sb, Hg and Cd were quantified in the surface sediments. Sediments were classified as non-polluted or polluted by counting the enrichment factor (EF), metal loading index (MLI) and geo-accumulation index (Igeo) based on the ele-mental background level of the analyzed elements in the literature, or by the Sediment Quality Guidelines (SQGs) of USEPA (United States Environmental Protection Agency). Based on USEPA's SQGs, the sur-face sediment in the entire Bay can be classified as heavily polluted by As and Cr, and non-polluted by Cd and Hg, and, related to the sites, the surface sediment at the Tivat-Arsenal site was heavily polluted and at the Orahovac site was not polluted at all. The PLI (pollution load index) values for the locations of Tivat-Arsenal and Orahovac are in agreement with the conclusion based on USEPA's SQGs. The results in this paper will establish an initial view of sediment pollution and the state of the Bay's environment.
