Indirect determination of microquantities of bromide ions in niobium germanide films by atomic absorption

This paper presents a procedure for the determination of bromide ions in niobium germanide films on a copper support, prepared by the reduction of niobium and germanium bromides with hydrogen. The amount of bromine in the analyzed solutions after sorption was assessed from the mercury content by multiplying the mercury concentration by a factor of 2. An atomic-absorption spectrophotometer was used in the work and the photocurrent was recorded by means of a standard compensation recorder. A high-frequency electrodeless mercury lamp served as the light source. In order to check the correctness of analysis and to determine the error of the developed procedure, ''added found'' tests were carried out with the use of six quartz columns
