An investigation of the determination of germanium by flame photometry and atomic-fluorescence spectroscopy by using a separated nitrous oxide-acetylene flame

Abstract

The flame photometry and atomic-fluorescence spectroscopy of germanium in a nitrogen and argon separated nitrous oxide-acetylene flame have been investigated. With the optimised operating conditions the detection limits at 265·1 nm were 1·1 and 0·1 p.p.m., respectively.

A germanium microwave-excited electrodeless discharge tube was prepared and used for excitation of the atomic fluorescence. The optimum conditions for the determination of germanium have been investigated, and the effects of elements commonly associated with germanium ores and the common inorganic acids were studied for interference.
