Selective Separation of Silver(I) Ion Through a Bulk Liquid Membrane Containing 1,1'-(1,3-Phenylene)bis(3-allylthiourea) as Carrier

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 ...

Separation Study of Silver(I) Ion through a Bulk Liquid Membrane Containing Meloxicam

Estudou-se o transporte ativo de íons Ag através de uma membrana líquida de clorofórmio contendo meloxicam. Avaliaram-se diferentes condições experimentais para aumentar a seletividade, sensibilidade e a velocidade de transporte, como por exemplo, efeito da concentração de meloxicam na membrana de clorofórmio, pH das fases doadoras e receptoras, tipos e concentrações de agentes removedores. Na ...

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...

Selective Transport of Propylene by Silver Ion Complex Through an Immobilized Liquid Membrane
