Direct flame atomic-absorption determination of minor elements in argillites.
The possibility of direct atomic-absorption determination of minor elements in argillites without preliminary concentration and separation is studied. The possibility is examined of producing an analytical flame zone in which free analyte atoms can be produced by use of chemical additives, such as potassium thiocyanate for molybdenum, and potassium thiocyanate plus dodecylamine hydrochloride for vanadium.
