Determination of Fe, Cu, Zn, Mn, and Pb in D.O.C. Méntrida wines
TLDR
In this paper, 14 wines from Mentrida (Toledo, Spain) were examined by atomic absorption spectrophotometry (AAS) in order to measure the concentrations of Fe, Cu, Zn, Mn, and Ph, using two different methods of sample preparation for the metal analyses: analysis of untreated samples and analysis of wet-mineralized samples.Abstract:
Fourteen wines from Mentrida (Toledo, Spain) were examined by atomic absorption spectrophotometry (AAS) in order to measure the concentrations of Fe, Cu, Zn, Mn, and Ph, using two different methods of sample preparation for the metal analyses: analysis of untreated samples and analysis of wet-mineralized samples. This was camed out in order to elaborate a suitable method for their determination after studying the possible matrix effects originating in either the organic or inorganic components. The influence of the vinification system on trace metal content and the stability and salubrity of these wines in relation to certain toxic metal concentrations was also examined.read more

Toxic trace metals in food. II. A comparative study of the levels of toxic trace metals in wine by differential pulse anodic stripping voltammetry and electrothermal atomic absorption spectrometry.
TL;DR: In this article, a new high performance analytical procedure for the determination of the toxic trace metals cadmium, lead and copper in wines by differential pulse anodic-stripping voltammetry (DPASV) subsequent to UV irradiation of the sample is compared with the hitherto more common application of electrothermal atomic absorption spectrometry (AAS) in this manner also mutually the accuracy attainable with both alternatives has been established.
