Abstract
The sodium salt of 6-tris(1-hydroxy-4-sulphonaphthyl-2-azo)pyrimidine
gives a 1:1 violet coloured complex with uranyl(II) at pH 5.5-6.5 in t
he presence of EDTA absorbing maximum at 560 nm, where no other metal,
including lanthanides, forms a complex. The Sandell's sensitivity of
colour reaction is 6.14 ngU(Vl)/cm(2). The developed method has been a
pplied to the determination of uranium(VI) in synthetic samples corres
ponding to mineral monazite and some uranium alloys.
