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.
