Table 1.

Colour, decomposition temperature, and pH of the uranyl complexes.

Sr. no. Complex Colour Decomposition temperature(°C) pH
(1) [UO2(Q)(Thr)·2H2O] Light Brown 265 7.00
(2) [UO2(Q)(Try)·2H2O] Light Brown 257 7.00
(3) [UO2(Q)(Iso)·2H2O] Light Brown 250 7.00

Where Q represents the deprotonated primary ligand 8-hydroxyquinoline, Thr, Try, and Iso represent deprotonated secondary ligands L-threonine, L-tryptophan, and L-isoleucine, respectively.
