Determination of Heavy Metal Interactions with Dissolved Organic Materials in Natural Aquatic Systems by Coupling a High-Performance Liquid Chromatography System with an Inductively Coupled Plasma Mass Spectrometer

Abstract: A high-performance liquid chromatographic (HPLC) system with a size exclusion column is coupled with an inductively coupled plasma mass spectrometer (ICP-MS) for the determination of interactions between heavy metals and different fractions of dissolved organic matter in natural aquatic systems. Direct coupling is applied to get specific distribution patterns of the heavy metal complexes, and on-line isotope dilution mass spectrometry is performed to quantify heavy metals accurately in different organic fract… Show more

“…Nevertheless, this approach is necessary in the experimental determination of the distribution of compounds that are labile with respect to the time scales of the analytical method. Recent literature indicates that high-performance liquid (HPLC) and gas chromatographic (GC) based techniques may have such capabilities (Batley and Low, 1989;Chau and Wong, 1989;van Loon and Barefoot, 1992;Kitazume et al, 1993;Rottmann and Heumann, 1994;Baxter and Frech, 1995;Szpunar-Lobinska et al, 1995;Ellis and Roberts, 1997;Vogl and Heumann, 1998). The ability to vary both the stationary and mobile phases, in conjunction with suitable detector selection (e.g.…”

“…79 This work highlighted the potential of size exclusion chromatography using an SF-ICP-MS (Element, Thermo Electron Corp., Bremen, Germany) for on-line speciation of Fe complexes in humic substances. Iron can now readily be measured using collision or reaction cell technology, 332 but SF-ICP-MS still offers the advantage of real spectral resolution from the interfering 40 Ar 16 O + on 56 Fe + at medium resolution power (R=3000).…”

“…Dependendo do tipo de água 51 , a concentração da substância húmica pode variar entre 0,1 e 115 mg L -1 . As propriedades físico-químicas dos metais pesados são alteradas pela interação com a matéria orgânica dissolvida e são, freqüentemente, influenciadas pelas propriedades da substância orgânica.…”
