Determination of iron and manganese in mineral waters of Galicia (Spain) by atomic absorption spectrophotometry
نویسندگان
چکیده
This paper describes the determination of Fe and Mn in thirty-six mineral waters of Galicia (NW Spain) by means of atomic absorption spectrophotometry (AAS) with an air/acetylene flame. In most cases iron was determined without modifying its concentration after checking its oxidation state in situ. Manganese was determined after concentration by evaporation. Recovery and reproducibility are good. In almost all samples the Mn/Fe ratio lies between 0,05 and 0,20.

Determination of lead, copper and manganese by graphite furnace atomic absorption spectrometry after separation/concentration using a water-soluble polymer.
In this study, a water-soluble polymer, polyvinylpyrrolidinone (PVP) having chelating functionalities was used for the preconcentration and separation of traces of Pb, Cu, Ve and Mn prior to their determination by graphite furnace atomic absorption spectrometry. For this purpose, the sample and the PVP solutions were mixed and the metal bound polymer was precipitated by adding the mixture onto ...
متن کاملEvaluation of Metal Levels of Drinking Waters from the Tokat-Black Sea Region of Turkey
The concentrations of chromium, nickel, copper, manganese, zinc, iron, cobalt and aluminum ions in drinking waters from eight sites of Tokat, Turkey, were determined by atomic absorption spectrometry. The values found the present work for the heavy metal contents of the drinking water samples of Tokat, Turkey were below the maximum tolerable limits set by the World Health Organisation (WHO) and...
متن کاملDetermination of urinary manganese by the direct chelation-extraction method and flameless atomic absorption spectrophotometry.
The direct chelation-extraction method, originally developed by Hessel (1968) for blood lead analysis, has been successfully applied to urinalysis for manganese. The analyses of 35 urine samples containing up to 100 microgram/1 of manganese from manganese-exposed workers showed that the data obtained by this method agree well with those by wet digestion-flame atomic absorption spectrophotometry...
متن کاملField sample preconcentration of copper in sea water using chelating minicolumns subsequently incorporated on a flow-injection-flame atomic absorption spectrometry system.
A field flow preconcentration system for copper determination in seawater is described. Seawater samples are collected and preconcentrated in situ by passing them using a peristaltic pump through a minicolumn packed with Amberlite XAD-4 impregnated with the complexing agent 1-(2-pyridylazo)-2-naphthol. Thus, copper is preconcentrated without the interference of the saline matrix. Once in the la...
متن کاملTrace elements and toxic metals in intensively produced tomatoes (lycopersicon esculentum).
INTRODUCTION Tomato is considered a healthy food due to its high content in lycopene and other health-promoting natural compounds. Tomatoes have, undoubtedly, assumed the status of a food with functional properties, considering the epidemiological evidence of reducing the risk of certain types of cancers. OBJECTIVE Samples of tomatoes from Morocco were analyzed for the mineral composition. ...
