“…With the appearance of chemometric methods, researchers are increasingly applying different mathematical algorithms to metal analysis to overcome the above mentioned problems of classical methods (e.g., low specicity and laborious sample preparation) (see, for example, ref. [3][4][5][6].…”

“…One of the most common methods for determination of metals is atomic spectroscopy (regardless of whether chemometric algorithms are used for modelling of experimental data or not). [4][5][6][7][8][9][10][11] A broad range of multivariate methods could be used either to directly quantify several metals or to interpret results of classical methods. For example, the combination of atomic emission spectroscopy with parallel factor analysis (PARAFAC), analysis of variance (ANOVA) or principal component analysis (PCA) is extremely helpful to increase efficiency of metal analysis.…”

“…For example, the combination of atomic emission spectroscopy with parallel factor analysis (PARAFAC), analysis of variance (ANOVA) or principal component analysis (PCA) is extremely helpful to increase efficiency of metal analysis. [4][5][6] Atomic absorption spectroscopy in combination with mixed-level orthogonal array design (OAD), factor analysis (FA) and cluster analysis (CA) was used to determine several transition metals (Cd, Cu, Fe, Ni, Pb, V and Zn) in atmospheric ne particles. 7 Also, CA, PCA, FA and discriminant analysis (DA) were successfully applied to the data of atomic absorption spectrometry for the examination of water quality in water reservoirs.…”

Determination of essential elements (Mn, Fe, Cu and Zn) in herbal teas by TXRF, FAAS and ICP‐OES

et al. 2021

The aim of this study was the comparison of the results obtained in the determination of the content of essential elements such as Mn, Fe, Cu and Zn in vegetation samples using different analytical approaches, including suspension preparation and total reflection X-ray fluorescence (TXRF) analysis as well as most commonly used spectroscopic methods in the field of vegetal analysis such as acid digestion in combination with atomic emission (AES) and atomic absorption spectrometry (AAS). In the case of TXRF analysis, two instruments equipped with different X-ray tubes anodes (W and Mo) were used to better evaluate the potential of TXRF for vegetal samples analysis. Analytical figures of merit for the considered methods were determined by the analysis of plant reference materials. The one-way analysis of variance (ANOVA) applied to the analysed and certified values showed that the results were not statistically different at the significance level of p-values <0.05. Therefore, suspension preparation and TXRF analysis proved to be a sustainable and fast analytical alternative to the most commonly used ones involving a previous digestion of the sample and inductively coupled plasma optical emission spectrometry (ICP-OES) or flame atomic absorption spectrometry (FAAS) analysis. Finally, the different analytical approaches were applied to the determination of Mn, Fe, Cu and Zn in a set of herbal teas used for medical purposes.

A Calibration Strategy for Stripping Voltammetry of Lead on Silver Electrodes

et al. 2010

View full text Add to dashboard Cite

This work presents a calibration strategy for stripping voltammetry which enables improving and testing accuracy, using as an example quantitative determination of lead ions on a silver electrode. The proposed procedure integrates the interpolative and extrapolative conventional calibration methods. In the proposed approach the accuracy of determination is verified by the evaluation of the statistical agreement of the results obtained in standard addition and a series of standard methodologies. In the experiments only the standard solutions used to perform quantification are required. The application of procedures of baseline subtraction may decrease the value of systematic error, therefore such an algorithm constitutes an essential part of the described methodology and has been given in detail. The proposed calibration strategy has been tested for the determination of Pb(II) ions in certified reference material (CRM) water samples.
