Dokumentationsfahne zu Heft 3 (1979) der ,,Acta hydrochimica et hydrobiologica" SCHURIG, H., und H. MULLER: Mechanisierte katalytisch- spektralphotometrisehe Eisenbestimmung im Trinkwasser uach dem ,,continuous-flow"-Prinzip. Acta hydrochim. hydrobiol. 7 (1979) 4, 281-288, 3 Abb., 3 Tab., 12 Lit. Verff. beschreiben ein spektralphotometrisches Eisenbe- stimmungsverfo.hrm, das die katalytische Wirkung des Eisens bei einer chemischen Beaktion der Farbstoffentwicklung nutzt. Die schr empfinciliche Untersuchungsmethode erfadt Eisen- konzentrationen zwischen 5 und 140 pg/l bei einer relativen Standardabweichung von + 5"/,. Am Probespeicher einer flow- stream-Apparatur wurde eine Rate von 30 Proben/h mit einem Probenspulverhaltnis von 1 : 3 eingestellt. Storionen mit ihren jeweiligen Grenzkonzentrationen sind tabellarisch erfadt; ihre Werte besitzen im Trinkwesser normalerweise nicht vertretene GroDenordnungen. SCHURIG, H., and H. MULLER: Mechanized Catalytic-Spectro- photometric Iron Detectiotr in Drinking Water According to the Continuous-flow Principle. The authors describe a spectrophotometric iron detection technique by which the catalytic action of iron in a chemical reaction of colour development is used. The highly sensitive method of analysis detects iron concentrations between 5 and 140 yg/l at a relative standard deviation of +ti?',,. On the sample store of a flow-stream apparatus a rate of 30 samples/h with a sample-wash ratio of 1 : 3 was set. Impurity ions
