This review discusses the results of research in the use of bulk liquid membranes in
separation processes and preconcentration for analytical purposes. It includes some …

Fumaric, malic and succinic acids have been selectively separated by facilitated pertraction
with Amberlite LA-2, using n-heptane as liquid membrane. The feed phase consisted on …

The mechanism of reactive extraction of rosmarinic acid with Amberlite LA-2 (secondary
amine) and D2EHPA (organophosphoric acid) was analyzed for three solvents with different …

Separation of rosmarinic acid by synergic reactive extraction using a mixture of two
extractants (one of aminic and one of basic type) dissolved in solvents with different …

Rosmarinic acid has been separated by facilitated pertraction with D2EHPA dissolved in
dichloromethane. The pertraction has been carried out in presence of 1-octanol, added into …

In this present paper the behavior of two important pharmaceutical compounds, namely:
nicotinic acid (vitamin PP/B3) and para-aminobenzoic acid (vitamin B10) to the transport …

p-Aminobenzoic acid has been facilitated pertracted with Amberlite LA-2 dissolved in
dichloromethane, using a U-shaped pertraction cell which allows obtaining the free liquid …

The influences of the pH-gradient between the feed and strip** phases and of carrier
concentration inside the membrane phase on the efficiency of facilitated pertraction of …

The influences of the pH-gradient between the feed and strip** phases and of carrier
