current-scan polarography at the ascending-water electrode ( awe ) was used to examine the electrochemical behavior of htta and la ( 3+ ) , both in the absence and presence of neutral ligands , topo or mbdpo , and the light this sheds on the mechanism of extraction of lanthanides with htta , as well as the role played by mixed-ligand chelate formation .
