摘要：
A photometric determination of rhenium as an alpha -furildioxime-complex in the presence of platinum in bimetallic catalysts is described. The rhenium is either determined directly without a previous separation of platinum, or the determination is performed by the extraction of the rhenium- alpha -furildioxim-complex with chloroform and a subsequent photometric measurement. Further the disturbing influences on the analysis by the elements V, Mo and W and the elimination of the latter by means of a preliminary extraction with alpha -bensoineoxime is reported.
