Transport Properties of Membranes on the Basis of Tetradecylammonium Associates with Complex Compounds Silver(I)-сefotaxime
Transport properties of the plasticized polyvinylchloride membranes on the basis of tetradecylammonium associates with complex connections silver (I) – cefotaxime in the conditions of a diffusive mass transfer and a direct current are investigated. With variation of concentration of electrode active substances (0.5; 1; 2; 3%), the external solutions contacting with membranes (10-2–10-7 M). It is established that resistance of membranes depends on the content of electrode active substances (EAS) and concentration of perimembrane solutions of a cefotaxime. When an increase in concentration of electrode active components, resistance of membranes decreases which is connected with an increase of a number of the ion-exchange centers in a membrane phase. The studied membranes are characterized by steady currents of conductivity for an appreciable length of time. Stationary values of potentials are established in 50 min from the beginning of measurement. The voltage drop on membranes remains constant with a change of the direction of current. It indicates that there is a reversible ion exchange on the border of the antibiotic membrane solution. It is shown that the introduction of modifiers (polyaniline and nanoparticles of NiZnFeO) reduces resistance of membranes which is connected to an increase in their conductivity. The permeability and streams of ions of antibiotics in membranes are estimated: these characteristics are not constant and specific properties of membranes; they depend on nature and the type of diffusing particles.
