The complex formation of U(VI), Np(VI) and Pu(VI) with chloride ions was studied in HClO4−HCl solutions at ionic strength of 2.0 and [H+]=2.0M by the method of extraction chromatography using dilute HDEHP as the stationary phase.

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.

Abstract The extraction of divalent zinc, cadmium and mercury from aqueous solutions containing lithium chloride using tri-n-octylphosphine oxide (TOPO) in benzene has been investigated. By applying the trial and error method of least-squares analysis to the equilibrium equation, M2+ (aq) + 2Cl− (aq) + 2TOPO (org) ⇆ MCl2 · 2TOPO (org), for these ...

Determining Stability Constants Using the AKUFVE Technique [PDF]
Solvent Extraction and Ion Exchange, 2019 The AKUFVE techniques were developed by Rydberg and co-workers in the 1960s. The main aim was to be able to perform a series of liquid-liquid extraction data varying one or more parameters and at the same time achieve very pure phases.

This contribution presents an experimental approach for improvement of analytical performance of electromembrane extraction (EME), which is based on the use of stabilized constant d.c. electric current. Extractions were performed using a high voltage power supply, which provided stabilized constant d.c.

Fulvic acids (FAs) were extracted by alkali extraction from different soil samples in China, then purified using resins and characterized by Fourier transform infrared spectroscopy. The complexing ability of FAs was investigated by measuring the stability constants of rare earth elements (REEs) (La(3+), Ce(3+), Sm(3+), Gd(3+), Y(3+)) with FAs by the ...

Abstract The activity coefficient of tri- n -octylamine (TOA) hydrochloride in benzene has been determined by a vapour pressure method and has been used in calculating the stability constants of the aqueous complexes of copper(II) and zinc(II) in hydrochloric acid solution from extraction experiments with TOA in benzene.

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
