A study on mass transfer model for cadmium extraction in emulsion liquid membrane system has been done. Mass transfer in the external phase and emulsion globule, stripping reaction, and diffusion of the complex were taken account into the model. Reaction and chemical equilibrium of the process were also considered. The partial differential equation was numerically solved using MATLAB software. Effect of some parameters such as acid concentration in the external phase, extraction speed, volume ratio of emulsion to feed phase, volume ratio of internal to membrane phase, and initial concentration to the extraction process were investigated and compared to the model. The model prediction can agree very well with the concentration profile of cadmium in each phase.

The separation of penicillin G from fermentation broth can be done by emulsion liquid membrane technique. The aim of this research is to establish the optimal conditions for the extraction and separation of penicillin G using emulsion liquid membrane technique. The optimal conditions were found to be at ratio of internal phase volume to membrane phase volume of 1:1 ; time of making emulsion, 1 min ; emulsion contact rate, 300 rpm; rate of stirring of emulsion, 2000 rpm ; rest time of emulsion, 13 min; concentration of  penicillin G as external phase, 375 ppm; and concentration of surfactant, 5% (v/v). pH of internal phase is 8; pH of external phase 5; ratio of emulsion phase volume to external phase volume, 1:2 and concentration of carrier 2 mM. The concentration of penicillin G and phenylacetic acid from fermentation results were 24771 mg/L and 32675 mg/L. Extraction by emulsion liquid membrane technique gave the percentage of penicillin G 53.38% and phenylacetic acid 60.41%. The percentage phenylacetic acid which is still higher (60.41%) indicated that the penicillin G could not completely be separated from phenylacetic acid by emulsion liquid membrane technique.   Keywords: penicillin G, fermentation, emulsion liquid membrane technique

A study was carried out to remove cadmium ions from a hydrochloric medium at a concentration of 100 ppm using the emulsified liquid membrane (ELM) technique. Emphasis was placed on assessing process parameters and their effect on changing the concentration of cadmium ions in the hydrochloric solution. To study the performance characteristics of the process, Taguchi method was used with analyzing of signal/noise ratio. Five parameters that affect performance such as (pH of the external phase (1-4), surfactant concentration in the organic layer (4% -10% v / v), carrier concentration in the organic layer (4% -10%  v / v), speed of  Emulsification (5800-24000) rpm and emulsion volume ratio / outer phase ratio (Eml./Ext ratio) was studied, taking into account the change in the concentration of cadmium ions in the external phase. To obtain the lowest concentration of cadmium ions in the external stage, the values ​​of the optimum parameters were: pH = 3, Surfactant conc. = 4%, Carrier conc. = 8% emulsification speed = 19700 rpm, and Eml./Ext.  ratio = 18%. Results of the present work suggested that Eml./Ext. ratio had a major effect on the concentration change, followed by a pH in the outer phase,  the emulsification velocity,  carrier concentration, and the surfactant concentration respectively.

Abstract In this research study, removal of zinc ions from the industrial wastewater was investigated using green emulsion liquid membrane technology. The liquid membrane was prepared by using waste cooking oil along with the surfactant, SPAN 80 and the internal phase, sulfuric acid. The extraction percentage of zinc increased with the increase in concentration of surfactant. The response surface methodology (RSM) analysis identified that the optimal variable values for the maximum extraction of zinc were: external pH – 3.8, surfactant concentration 4% (vol.), internal phase concentration – 1.61N, zinc concentration – 742 mg/L, external phase to emulsion volume ratio – 0.94 and carrier concentration – 8.9%. At the optimized conditions experiment was carried out and the maximum extraction was found to be 97.4%. The perturbation plot shows that the extraction of zinc was affected by variables in the following order of effect: zinc concentration > surfactant concentration > carrier concentration > external pH > external phase to emulsion volume ratio > internal phase concentration.

The aim of this research is to quantify the occurrence of membrane breakage in vegetable oil based Emulsion Liquid Membrane (ELM). Basically, ELM consists of three main phases; internal, external and membrane. In this work, the membrane phase was prepared by dissolving Span 80 as surfactant and Aliquat 336 as carrier in commercial grade corn oil. As a way to promote sustainable development, vegetable oil which is environmentally benign diluent was incorporated in the formulation of ELM. The influence of several important parameters towards membrane breakage were studied. They are carrier and surfactant concentration, W/O volume ratio, emulsification time, internal phase concentration as well as stirring speed. Based on the data obtained, emulsion prepared using 4 wt% Aliquat 336 and 3 wt% Span 80 resulted in the most stable emulsion with only 0.05% membrane breakage. The emulsion was produced using W/O volume ratio of 1/3 and it was homogenized with the assistance of ultrasound for 15 min. Moreover, emulsion produced able to provide a fair balance between emulsion stability and Cd(II) permeability as it able to remove 98.20% Cd(II) ions from the external phase.
