โœฆ Synopsis

The complex formation reaction between some aliphatic amines and uranyl(VI) ion in dimethylsulfoxide has been investigated by polarographic and spectrophotometric methods. Primary amines such as n-butylamine and n-hexylamine give a distinct cathodic wave which may be discussed in term of the successive l:l, 2:l and 3:l amine uranyl( VI) complexes formation. On the contrary tert-butylamine gives two distinct cathodic waves; the first indicates the existence of the stable 1:1 complex, while the second is attributable to the 2:l and 3:l amine uranyl(VI) complexes. Secondary straight-chain amines qualitatively behave as primary straight-chain amines. Tertiary amines show a poor coordinating ability for uranium-(VI) and only triethylamine suggests the ultimate formation of the 3:l complex. The coordinating abilities of the amines studied decrease in the series
