Summary

3-Phenyldaphnetin (3-phenyldihydroxycoumarin) in ethanolic solutions forms water-soluble orange-yellow-coloured complex with uranium (VI) solutions. The complex obeys Lambert-Beer’s law up to 9 p.p.m. of uranium in solution and has the composition 1:1. Stability constant of the complex has been determined and concentration limits of interfering ions that can be tolerated have been stated. A possible use of 3-phenyldaphnetin for the spectrophotometric estimation of uranium (VI) has been suggested.
