2-ethylhexyl phosphonates

This technique has been used to study the extraction kinetics of rare-earth elements from an aqueous phase into heptane by 2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester (HEH/EHP) [31]. The linear dependence of f c ) on t in Fig. 5 was considered to indicate that the extraction of ErCl3 by HEH/EHP is a diffusion-controlled process.

A variant solvent formulation was developed in China (INET), involving (2-ethylhexyl)-phosphonic acid 2-ethylhexyl ester (HEHEHP) as the extractant (saponified to 40% with concentrated ammonia), dissolved at 1.5 M in kerosene, to recover, in 43 stages, 99% of Am(III) and remove 90% of Ln(III) from a 0.2 M nitrate feed (pH 1) (237).

Organophosphorus extractants such as di(2-ethyl-hexyl) phosphoric acid (DEHPA), 2-ethylhexyl-phosphonic acid mono-2-ethylhexyl ester (EHPA), N-benzoyl-A-phenylhydroxylamine (BPHA), and tetra-octylethylenediamine (TOEDA) are often used due to their solubility properties in the stationary organic phase [1-3].

This is a detailed study of the extraction equilibria in the toluene-Th(lV)-hydrogen 2-ethylhexyl phosphonate-Cl - NO3 systems. There is no quantitative information on the formation of complexes between thorium and Cf or NOj in the aqueous phase, only a qualitative statement that Th(NOj and Th(NOj )l " complexes are extracted to a much greater extent than the corresponding chloride complexes. 

Technetium, one of the key elements in the treatment of radioactive liquid waste, because of its long half-life and geochemical mobility, was separated from concentrated alkaline solutions by SLMs containing 2-nitrophenyloc-tyl ether (NPOE) [180]. The hollow-fiber SLM, containing bis(2-ethylhexyl)phosphonic acid, was tested for carrier-free separation of from °Sr [181].
