In the literature review different solid sample preparation methods were compared with special attention to their residual carbon amounts. In addition, ICP theory, equipment and interferences, especially those of carbon, were presented. In the experimental section of this work, matrix effects of carbon at residual amounts on trace elements of plastic materials (As, Cd, Cr, Pb, Sb, Sn, Zn, S) were evaluated. Synthetic samples with different carbon matrixes were prepared with certified plastic materials as a template. Optimal measuring parameters for carbon containing samples on inductively coupled plasma optical emission spectroscopy (ICP-OES) were determined. These conditions were further utilized in analysis of certified reference materials. Carbon matrix containing samples were measured with ICP-OES as well as inductively coupled plasma mass spectrometry (ICP-MS). In addition, possible cooperative action of carbon and easily-ionized-elements (EIE), were investigated with ICP-OES. It was concluded that residual amounts of carbon have no significant effect on the investigated elements in plasmas in question. The emission of tin in ICP-OES was observed to drop by 50 % in precence of 5000 mg/l of carbon and 200 mg/l of EIE matrix. According to these results the analysis of the investigated elements can be performed with confidence utlizing these evaluated methods.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Tuukka Niskanen (tutanisk) on 2017-09-12 11:30:58.514400.
