Transport and separation through bulk liquid membrane of some biologic active compounds

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 ...

Kinetics of Cu (II) Transport through Bulk Liquid Membrane with Different Membrane Materials

The kinetics of Cu(II) transport through a bulk liquid membrane with different membrane materials was investigated in this work. Three types of membrane materials were used: fresh cooking oil, waste cooking oil and kerosene, each of which was mixed with di-2-ethylhexylphosphoric acid (carrier) and tributylphosphate (modifier). Kinetic models derived from the kinetic laws of two consecutive irre...

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 ...
