FIELD: analytical chemistry.
SUBSTANCE: method can be used for determining content of bismuth in copper-based alloys. Bismuth solution (III) is prepared, transferred into complex compound and diffuse reflection factor is measured. Bismuth is selected due to transferring it into complex compound from 0,5-3 M solution of hydrochloric acid by means of sorbent - silica, chemically modified N-allyl-N'-propylthiocarbamide. Diffuse reflection factor of bismuth (iii) complex is measured when taking N-allyl-N'-propylthiocarbamide on the surface of silica.
EFFECT: simplified procedure of measurement; widened range of concentrations to me measured.
