Transport through Liquid Membrane, Containing Ammonio=Imidates as Carrier Molecules

Kinetics of Chromium(III) Transport Through a Liquid Membrane Containing DNNSA as a Carrier

Kinetics of Cr(III) ions transport through a bulk liquid membrane containing dinonylnaphthalenesulfonic acid (DNNSA) as a carrier, flowing over aqueous phases, has been examined. Special attention has been paid to the effect of the membrane's velocity flow on the chromium concentration decrease in a feed phase. For the description of relationships of chromium(III) concentration in particular ph...

A Kinetic Investigation of a Carrier-Mediated Transport through a Bulk Liquid Membrane

The kinetics of the potassium thiocyanate transport mediated by dicyclohexyl-18-crown-6 (L) through a bulk liquid membrane is studied experimentally and theoretically. The proposed model is based on the assumption of a pure diffusion of the complex salt [K·L]+SCN¯ through the liquid membrane stagnant films at the interfaces. It illustrates the ...

Extractive Resolution of Racemic Mandelic Acid through a Bulk Liquid Membrane Containing Binary Chiral Carrier

Um método empregando “bulk liquid membrane” (BLM) e o complexo ácido di(2-etilhexil) fosfórico (D2EHPA) e ácido O,O’-dibenzoil-(2R, 3R)-tartárico (L-(-)-DBTA) foi desenvolvido para a separação por extração do ácido mandélico racêmico (rac MA). Os efeitos de tempo de resolução, concentração de D2EHPA na fase orgânica, concentração de rac MA na fase doadora, velocidade de agitação e temperatura s...
