Asian Journal of Chemistry, 27(4), 1540-1542.0970-7077https://doi.org/10.14233/ajchem.2015.18795https://hdl.handle.net/11468/23611The search for a rapid dissolution technique has lead several workers to investigate the use of a microwave oven as a heat source in a low temperature digestion system. In this study, three different copper ore samples from the Tigris river basin (Turkey) and the river sediment were digested by microwave radiation and recoveries of four elements (Co, Cu, Ni, Zn) were compared to those by the hot plate conventional method. The samples were digested with mixtures of hydrochloric acid, nitric acid and hydrofluoric acid. The concentrations of metal ions were determined by Perkin Elmer Optima 2100 DV inductively coupled plasma-optical emission spectrometry (ICP-OES). Analytic recoveries were equivalent to the standard hot plate method after a microwave digestion of only for few minutes.eninfo:eu-repo/semantics/openAccessCopper oresDeterminationDigestionHeavy metalMicrowaveSedimentArticle27415401542WoSIDEksik2-s2.0-8496462023710.14233/ajchem.2015.18795Q4N/A
