| Abstract: | The Rose Bengal forms with cationic surfactants /1-carbethoxypentadecyltrimethyl-ammonium bromide, cetyltrimethylammonium bromide and cetylpyridinium bromide/ the extractable ion associates with composition 1 1 or 12. The extraction constants of the ion associates of the Rose Bengal with cationic surfactants were determined radiometrically with the aid of Rose Bengal labelled with131I. |
