摘要:

A method for the spectrophotometric determination of bismuth is described. The method is based on using polyether polyurethane foam sorbent as a favourable matrix. Sorption of the bismuth iodide complex into the foam thin layer contributed into substantial improvement of the measured absorbance value of the coloured species. In this way quite satisfactory results were achieved, the average recovery amounts to 105.25%.
