Chemical analysis is a well-established procedure for the provenancing of archaeological ceramics. Various analytical techniques are routinely used and large amounts of data have been accumulated so far in data banks. However, in order to exchange results obtained by different laboratories, the respective analytical procedures need to be tested in terms of their inter-comparability. In this stu...

Heavy metals in textile wastewater represent a major environmental problem, and are a potential danger to human health when present on textiles. Furthermore, the presence of some metals influences the production of textiles. Heavy metals are often used as oxidizing agents, as metal complex dyes, dye stripping agents, fastness improvers, and finishers. Thus, they act as hazardous sources through...

Legislation limits for risk elements (As, Be, Cd, Co, Cr, Cu, Ni, Pb, V, Zn) in agricultural soil the Czech Republic are given content of extracted by aqua regia. This extraction is time consuming and environmentally unfriendly. The regular survey based on Mehlich 3 universal extractant covers simultaneous determination macronutrients, sulphur, micronutrients inductively coupled plasma optical ...

A nagyműszeres analitikai vizsgálatok eredményeinek megbízhatóságát a minőségbiztosítási rendszer eszközei hivatottak garantálni. Jelen dolgozatban az emberi hibákból és más apró mulasztásokból adódó, így szabványtól eltérő eredményességét vizsgáljuk ICP-OES, illetve annak visszaellenőrzésére szolgáló FAAS módszerekkel. Egy ismeretlen összetételű talajmintát vizsgáltunk egy ismert referencia ta...

The combinations of inductively coupled plasma-optical emission spectrometry (ICP-OES) and three classification algorithms, i.e., partial least squares discriminant analysis (PLS-DA), least squares support vector machine (LS-SVM) and soft independent modeling of class analogies (SIMCA), for discriminating different brands of Iranian bottled mineral waters, were explored. ICP-OES was used for th...

This paper reviews the current research on the speciation and determination of mercury by various analytical techniques, including the atomic absorption spectrometry (AAS), voltammetry, inductively coupled plasma optical emission spectrometry (ICP-OES), ICP-mass spectrometry (MS), atomic fluorescence spectrometry (AFS), spectrophotometry, spectrofluorometry, and high performance liquid chromato...

The advent of rare earth elements (REEs) with optoelectronic properties has shifted the technology paradigm from digital to a smart and hybrid world. Their substantial uses also resulted in large piling up e-waste. Therefore, e-waste is now lucrative recycling target for recovery such critical raw materials. often challenged by dilute metal concentration, complex composition, difficult chemical...

Inductively coupled plasma optical emission spectrometry was applied to the determination of trace impurities in tantalum powder. The matrix effects of tantalum in the determination of trace level impurities such as Cr, Fe, Nb, Ni, and Ti were studied by measuring the intensities of each trace element in solution at various concentrations of tantalum. As the concentration of the interfering ele...

A new hyphenated method was developed for the speciation of Tl. In this method, Tl(III) was complexed with DTPA to form a Tl(III)-DTPA anionic complex. Tl(I) did not form a complex with DTPA. The two species were separated simultaneously by means of ion chromatography using a Dionex cation exchange guard column, CG12A, and 15 mmol/l nitric acid as eluant. When ICP-OES was used as detector the d...
