Zur quantitativen Bestimmung von Spurenelementen auf spektrochemischem Wege

Abstract: Wahrend die Makronahrstoffe im Boden heute durch leistungsfahige Methoden mit genugender Genauigkeit und Schnelligkeit ermittelt werden konnen, verlangt die Bestimmung der Spurenelemente zur Zeit noch sehr umstandliche und darum zeitraubende Analysengange. Zwar gestatten die polarographischen und vor allem die photometrischen Verfahren teilweise einen sehr empfindlichen Nachweis, doch erioi-dern sie einen verhaltnismafiig hohen Zeitaufwand pro Analyse.Ein Verfahren, das demgegenuber die Moglichkeit des empfind… Show more

“…Trace elements in soils and other materials have been separated and concentrated by extraction of the metal pyrrolidine dithiocarbamate complexes in chloroform followed by emission spectrographic estimation (179). The technique permits the simultaneous determination of a large number of elements.…”

“…In soil analysis, various methods were reviewed (171), methods for the analysis of soils and biological materials were described (221), a direct current arc total-energy method is used in plant nutrition and soil investigation (225), and the determination of trace elements after extraction from soils is reported (214). Methods employed at the Macaula)^I nstitute for Soil Research are reviewed (173) and analyses of plant materials, water, and soil extracts in plant nutrition studies are described (244).…”
