"Metal Species Determination By Ion Chromatography"
Trends Anal. Chem. 2001 Volume 20, Issue 6-7 Pages 304-310
Corrado Sarzanini and Maria Concetta Bruzzoniti

Abstract: Liquid chromatography has become one of the main powerful analytical tools for the analysis of complex matrices and speciation studies in the field of metal analysis. The basic principles, retention mechanisms, materials and method evolutions are discussed with particular reference to ion chromatography, Classical and more recent applications are presented.

"Preconcentration Of Contaminants In Water Analysis"
J. Chromatogr. A 2000 Volume 902, Issue 1 Pages 289-309
Maria Concetta Bruzzoniti, Corrado Sarzanini and Edoardo Mentasti

Abstract: Among the environmental areas, in this review attention will be focused on water matrices and both on organic (e.g., pesticides, herbicides, phenols, polycyclic aromatic hydrocarbons), inorganic species and anion pollutants, since these kinds of substances include a wide number of compounds with different physical and chemical properties and different effects on human health. Analytical methods for control of quality of waters are required to be highly specific and possibly highly sensitive for the determination of even low amounts of pollutants. The main problems encountered during the analysis are the separation of matrix components from the pollutants of interest and the achievement of low detection Limits. Therefore an overview on different materials and techniques available for sample concentration and/or matrix removal will be provided and discussed according to the chemical characteristics of the pollutant that has to be enriched.

"Flow Injection Preconcentration And Electrothermal Atomic Absorption Spectrometry Determination Of Manganese In Seawater"
Anal. Chim. Acta 2001 Volume 435, Issue 2 Pages 343-350
Corrado Sarzanini, Ornella Abollino and Edoardo Mentasti

Abstract: A procedure for the determination of manganese in seawater by flow injection pre-concentration coupled to electrothermal atomic absorption spectrometry was developed. The analyte is complexed by 1-(1-hydroxy-2-naphthylazo)-6-nitro-2-naphthol-4-sulphonic acid (Eriochrome Black T), its complexes are retained onto an anion exchange resin, and eluted with hydrochloric acid. A software driven pre-concentration apparatus was set up and a new housing for the enrichment column was designed and adopted. After studying the effect of acidity and ligand concentration, the accuracy of the procedure was assessed by analysis of certified seawater.

"Ion-chromatographic Separation And Online Cold Vapor Atomic Absorption-spectrometric Determination Of Methylmercury, Ethylmercury And Inorganic Mercury"
Anal. Chim. Acta 1994 Volume 284, Issue 3 Pages 661-667
Corrado Sarzanini*, Giovanni Sacchero, Maurizio Aceto, Ornella Abollino and Edoardo Mentasti

Abstract: The ion chromatographic separation of methylmercury, ethylmercury and inorganic mercury as cysteine complexes was investigated. The chromatographic apparatus was interfaced with cold vapor atomic absorption spectrometry for detection using an on-line continuous flow cell coupled with a reduction system (sodium tetrahydroborate). The influence of the composition of the eluent (pH, ionic strength, cysteine concentration) and stripping gas flow-rate was investigated. The method was optimized by coupling an on-line pre-concentration step. The detection limits, evaluated on 100.0 mL samples, were 2, 10 and 4 ng for Hg, CH3Hg and C2H5Hg, respectively. The method was applied to synthetic mixtures and natural samples (tap water) and furnished satisfactory results.
