    • Abstract


      Chrysin forms a yellow coloured complex with thorium. This colour reaction has been investigated and utilised for spectrophotometric determination of thorium. The colour has maximum intensity at pH 2·8. It obeys Beer-Lambert’s law at 380 mµ between the concentration limits of 2 and 36 p.p.m. of thorium. The molar composition of the complex has been found to be 1:1.
