Characterization of Metal Complexation in Multiligand Systems with Lanthanide Luminescence.

Journal of colloid and interface science

Martínez GA, Traina SJ, Logan TJ.
PMID: 9665764
J Colloid Interface Sci. 1998 Aug 01;204(1):33-44. doi: 10.1006/jcis.1998.5573.

The effectiveness of an Eu3+ luminescence technique to describe metal complexation reactions in humic substances was evaluated. The molecular uncertainties intrinsic to humic substances were circumvented by using polyacrylic acid (PAA) and polyvinylsulfonic acid (PVS) as probes. An adequate...
