ISSN: 1432-1130Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract The development of an apparatus for the on-line sampling, digestion and quantification of total mercury in surface water is described. Detection and quantification is done by flow injection cold vapor atomic absorption spectroscopy (FI-CVAAS). Three digestion methods were tested, chemical, microwave and UV. The influence of the digestion parameters (digestion method, digestion time, microwave power, concentration of oxidation solution) on the recovery of mercury in water of the river Elbe have been investigated. Mercury can be determined almost quantitatively (recovery rate 〉 85%) with some digestion procedures described. The best results were reached by UV digestion. The technique is fast, simple ¶to handle and robust. Each complete analysis only take four minutes. The working range is 10 to 1000 ng/L. The measuring arrangement has been applied successfully in a governmental monitoring station at Schnackenburg/Elbe, Germany.Type of Medium: Electronic ResourceURL:
