An overview on pollutants removal from aqueous solutions via bulk liquid membranes (BLMs): Parameters that influence the effectiveness, selectivity and transport kinetic

Penetration of model solid particles (polymer, teflon, nylon, alumina) into transparent model liquids (distilled water and aqueous solutions of KI) were recorded by a high speed (500 frames per second) camera, while the particles were dropped from different heights vertically on the still surface of the liquids. In all cases a cavity has been found to form behind the solid particle, penetrating into the liquid. For each particle/liquid combination the critical dropping height has been measured, above which the particle was able to penetrate into the bulk liquid. Based on this, the critical impact particle velocity, and also the critical Weber number of penetration have been established. The critical Weber number of penetration was modelled as a function of the contact angle, particle size and the ratio of the density of solid particles to the density of the liquid.

This paper presents a transport and recovery of silver ions through bulk liquid membranes based on n–decanol using as carriers 10–undecylenic acid and 10–undecylenyl alcohol. The transport of silver ions across membranes has been studied in the presence of two types of magnetic oxide nanoparticles obtained by the electrochemical method with iron electrodes in the electrolyte with and without silver ions, which act as promoters of turbulence in the membrane. Separation of silver ions by bulk liquid membranes using 10–undecylenic acid and 10–undecylenyl alcohol as carriers were performed by comparison with lead ions. The configuration of the separation module has been specially designed for the chosen separation process. Convective-generating magnetic nanoparticles were characterized in terms of the morphological and structural points of view: scanning electron microscopy (SEM), high-resolution SEM (HR–SEM), energy dispersive spectroscopy analysis (EDAX), Fourier Transform InfraRed (FTIR) spectroscopy, thermal gravimetric analysis (TGA), differential scanning calorimetry and magnetization. The process performance (flux and selectivity) was tested were tested for silver ion transport and separation through n–decanol liquid membranes with selected carriers. Under the conditions of the optimized experimental results (pH = 7 of the source phase, pH = 1 of the receiving phase, flow rate of 30 mL/min for the source phase and 9 mL/min for the receiving phase, 150 rot/min agitation of magnetic nanoparticles) separation efficiencies of silver ions of over 90% were obtained for the transport of undecenoic acid and about 80% for undecylenyl alcohol.

ABSTRACT The removal of Cu(II) from aqueous solutions had been employed throught bulk liquid membrane techniques with arrange the optimization conditions of transport Cu(II) interface system. The optimum conditions of transport were found to be 3.1510-4 M of Cu(II) at pH 3 in the source phase, 17.510-4 M oxine dissolved into chloroform as membrane phase, 0,15 M H2SO4 as acceptor in receiving phase, stirring rate was 340 rpm and it was found that the transport of Cu(II) to receiving phase reached 97.41% during 6 hours. The effect of addition oleat acid 1.57 10-3 M as surfactant in membrane phase resulted a rapidly time of transport Cu(II) to be 3 hours, wherein Cu(II) transported into the receive phase reached 97.83% and remained in feed phase 0%.

ABSTRACT Determination of kinetic analysis of Co(II) ion transport through bulk liquid membranes by consecutive method have been study. The optimum condition was obtained at pH 4 for the intermediate phase and receiving phase at pH near zero, while the source phase at pH 7, oxine concentration in chloroform at source phase is 2.10 M, methyl red concentration in chloroform at receiving phase is 3.10 M. It was found that Co(II) ion receiving phase at optimum condition as 4.40%. Evaluation of Co(II) ion kinetic transport shows k1 as 0.0116 minutes-1 and k4 0.0113 minutes-1. Kinetic transport process of Co(I1) ion through bulk liquid membranes by consecutive method followed first order consecutive irreversible reaction rate low. Consecutive method can used as an alternative method in determination the optimum condition of metals ion transport and kinetic evaluation of mentioned transport metals ion.
