摘要: A novel microwave-assisted wet-acid decomposition method for the multi-element analysis of glass samples using inductively coupled plasma atomic emission spectrometry (ICP-AES) was developed and optimized. The SRM 621 standard reference material used this purpose, because it has similar composition with either archaeological specimens or common modern glasses. For main constituents (Ca, Na, Al, Fe, Mg, Ba Ti), quality control data are given all examined procedures. chemical instrumental parameters were thoroughly Thirteen acid mixtures hydrochloric, nitric, hydrofluoric acids in relation to two different microwave programs order establish most efficient protocol determination metals matrix. both programs, an intermediate step employed addition H(3)BO(3) compensate effect HF, which protocols. suitability investigated protocols evaluated major Al), minor (Fe, Ba, Ti, Mn, Cu, Sb, Co, Pb) constituents. analytes determined matrix matched solutions. analytical processed chemometrically evaluate terms their accuracy, precision sensitivity, eventually select ancient glass. ICP-AES such as spectral line, RF power sample flow rate optimized proposed protocol. Finally, optimum successfully applied a number fragments.
