“…There are eight different possibilities for the connection of the first ligand in the case of both the bi and tridentate ligands [17] since a tridentate ligand occupies three coordination sites, there is only one possibility for the coordination of a further tridentate ligand, and two possibilities for a bidentate one. If the first ligand to be coordinated is bidentate, then there either are two possibilities for the coordination of a further bidentate or tridentate ligand too.…”

Removal of oversupply of toxic metals has been accomplished medically by the addition of metal chelators. Metal chelators, while useful, have many disadvantages, one of which is the undesired complexation and removal of other essential metals. In the reverse sense, metals are capable of ligand scavenging or mixed complex formation. The degrees to which metal ions can chelate greatly depend on the various chemical factors like stability, solvent nature, ionic strength and statistical ratio etc. In this review, we provide update covering above-said factors, biological importance and recent methods leading chelation (Figure 1).

In this paper we report the results of an investigation performed by potentiometric (H+-glass electrode) and visible spectrophotometric measurements on the interaction of UO2(2+) ion towards some carboxylic ligands (acetate, malonate, succinate, azelate). The measurements were carried out at T= 25 degrees C in different ionic media (KNO3 and NaCl) at different ionic strengths (0.1 < or = I/mol L(-1) < or = 1.0, NaCl; I/mol L(-1) = 0.1, KNO3). The dependence on ionic strength of formation constants was taken into account by using both a simple Debye-Hückel type equation and the SIT (Specific ion Interaction Theory) approach. Different speciation models (depending on concentration of reagents, ionic strength, pH-range) both for different carboxylates and different ionic media have been obtained. Linear combinations between formation constants, stoichiometric coefficients and length of alkyl chain of dicarboxylates have been observed and predicted formation constants at I= 0 mol L(-1) are reported for the interaction of UO2(2+) with HOOC-(CH2)n-COOH with 1 < or = n < or = 7. Finally, a visible absorption spectrum for each complex reaching a significant percentage of formation in solution (KNO3 medium) has been calculated to characterise the compounds found by pH-metric refinement.
