Complexation Capacity and Conditional Stability Constants for Copper of Sea- and Estuarine Waters, Sediment Extracts and Colloids

1984
Trace metals in the environment occur in a variety of forms in solution, in colloids and particulates. Speciation studies try to distinguish between different dissolved forms (valence state, ionic, (in)organic complexed). Speciation has become important in studies concerning transport processes and the fate of trace elements. The toxic effects of trace

The Influence of Alkyl Chain Length and Steric Effect on the Stability Constants and Extractability of Co(II) Complexes with 1-Alkyl-2-Methylimidazoles

Separation Science and Technology, 2014
Using the liquid-liquid partition method, the formation of Co(II) complexes with 1-alkyl-2-methylimidazoles (where alkyl = C4H9 trough C12H25) at 25°C and at a fixed ionic strength of the aqueous phase (I = 0.5, (HL)NO3, KNO3) were studied. Dichloromethane, trichloromethane, and 2-ethylhexanol were used as diluents.

High selectivity, capacity and stability for electrochemical lithium extraction on boron-doped H1.6Mn1.6O4 by tailoring lattice constant and intercalation energy

Water Research
A sustainable supply of lithium from salt-lake brines is necessary due to the surge in demand of the lithium-battery market. However, the presence of coexisting ions, particularly Na+, poses a significant challenge due to the similarities in charge, electronic structure, and hydrated size.

Stability constants and free energies of complexation of metal-ion cryptates in nitromethane. Derived parameters for the extraction of cations by cryptand 222 from water to pure nitromethane

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1985
Stability constants have been measured and free energies of complexation of alkali-metal and silver cations in nitromethane at 298 K have been derived. The results obtained in this solvent are compared with corresponding data in different reaction media. Free energies of transfer of metal-ion cryptates from water to nitromethane are derived.
