Determination 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...

Determination of iron and manganese in mineral waters of Galicia (Spain) by atomic absorption spectrophotometry

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 goo...

High-speed automated atomic absorption spectrophotometry.

We describe an integrated automated system for the atomic absorption spectrophotometer. The system makes use of a light-dependent resistor to detect the presence of a marker ion which is present along with the sample ion in the flame. An electronic circuit has been developed which enables the marker ion to trigger the read signal of the spectrophotometer. The system has been tested by determini...

Comparative sensitivities of flame atomic absorption spectrophotometry (AAS) and molecular absorption spectrophotometry (MAS).

A sensitivity comparison was made between conventional atomic absorption spectrophotometry (AAS) and conventional molecular absorption spectrophotometry (MAS) for the serum trace metals, copper, iron, and zinc. The sensitivity aspect considered was absorbances was obtained for concentrations in the solutions analyzed using unit lightpaths of 1 cm and 10 cm for MAS and AAS, respectively. A disti...
