    M02.006 Quantitative photometric determination of iron after derivatisation
    (2017-11-27)
    Fütterer, Cordula
    ;
    Stahl, Alina
    Determination of Fe (II) is carried out by means of 1,10-phenanthroline taking advantage of the fact that Fe (II) forms a water soluble red complex with 1,10-phenanthroline. The intensity of the coloured species is measured by a photometer. The concentration in samples is quantified with an external calibration and results are reported in mg/l.

    M02.003 Quantitative determination of mercury in solid samples by atomic absorption spectroscopy
    (2017-04-18)
    Fütterer, Cordula
    ;
    Stahl, Alina
    Determination of mercury(I) and (II) in solid samples such as soil, sludge or sediment is carried out by means of a flow injection mercury system (FIMS) which uses atomic absorption as detection (AA). After digesting and the solid samples, tin(II) chloride reduces Hg2+ to elementary mercury. This elementary mercury can be analysed by FIMS at the wavelength of 253,7 nm. The concentration in samples is quantified with an external calibration and results are reported in µg/kg or mg/kg.

    M02.004 Quantitative determination of mercury in aqueous samples by atomic absorption spectroscopy
    (2017-04-18)
    Fütterer, Cordula
    ;
    Stahl, Alina
    Determination of mercury(I) and (II) in different types of water such as potable water, surface water, rainwater and wastewater is carried out by means of a flow injection mercury system (FIMS) which uses atomic absorption as detection (AA). To oxidize the mercury in its divalent form, aqueous samples are treated with KBr- KBrO3. After that, tin(II) chloride reduces Hg2+ to elementary mercury. This elementary mercury can be analysed by FIMS at the wavelength of 253,7 nm. The concentration in samples is quantified with an external calibration and results are reported in µg/L or mg/L.
