Extraction of silver (I) has been studied from black/white printing photographic waste by emulsion liquid membrane technique. Composition emulsion at the membrane phase was cerosene as solvent, sorbitan monooleat (span 80) as surfactant, dimethyldioctadesyl-ammonium bromide as carrier and as internal phase was HNO3. Optimum condition was obtained: ratio of internal phase volume and membrane phase volume was 1:1 : concentration of surfactant was 2% (v/v) : time of making emulsion was 20 second : rate of stiring emulsion was 1100 rpm : rest time emulsion was 3 second : rate of emulsion volume and external phase volume was 1:5 : emulsion contact rate 500 rpm : emulsion contact time was 40 second : concentration of silver thiosulfate as external phase was 100 ppm : pH of external phase was 3 and pH of internal phase was 1. Optimum condition was applied in silver(I) extraction from black/white printing photographic waste. It was obtained 77.33% average which 56.06% silver (I) average of internal phase and 22.66% in the external phase. Effect of matrices ion decreased silver(I) percent extraction from 96,37% average to 77.33% average. Keyword: photographics waste, silver extraction

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

The purpose of this study was to investigate the extraction of lead by emulsion liquid membrane as an effective alternative to conventional lead extraction methods. The emulsion included D-2-ethylhexyl phosphoric acid (D2EHPA) as a carrier, paraffin and kerosene composition as an organic solvent, Span 80 as an emulsifier and sulfuric acid as an internal stripping phase. In this project, 7 effective factors in extraction of lead were chosen by emulsion liquid membrane, which included concentration of sulfuric acid in the internal phase, volume ratio of the emulsion to external phase (Rew), the ratio of organic phase to internal phase (Roi), initial pH of external phase, contact time of the emulsion and external phase, carrier concentration and concentration of surfactant in the membrane phase. After the initial experiments to make a stable emulsion, membrane phase mix (70% paraffin and 30% kerosene), homogenizer speed (12000 rpm) and mixer speed (309 rpm) were selected. The final experiments were designed by Taguchi statistical method. Optimization was done according to higher extraction rate and the effect of each of these factors and their optimal values as well as optimal conditions were determined. By verification test, it was shown that more than 92% of lead can be extracted from a solution with a concentration of 2000 ppm.

The effects of cadmium(II) and nickel(II) ions to copper(II) extraction using liquid membrane emulsion with 4-benzoyl-3-methyl-1-phenyl-2-pyrazolin-5-on (HPMBP) as an extractant was studied. The optimum condition forcopper(II) extraction were as follows: emulsification rate=2000 rpm, emulsification time=10 minutes, extractionrate=300 rpm, extraction time=15 minutes, concentration of mixed surfactant (span 80+span 20)=3%, volumeratio of membrane phase and internal phase=1:1, concentration of HPMBP=0.020 M, concentration of HCl=1M,volume ratio of emulsion and external phase=1:7. The result showed that the extraction of copper(II) by liquidmembrane emulsion with HPMBP as an extractant was selective to cadmium(II) and nickel(II) ions, relatively. Theresult also showed that in the extraction of 500 mg/l copper(II), the presence of 500 mg/l of nickel(II) was decreasingthe percentage of copper(II) extraction to be 83.73. While, the presence of 500 mg/l of cadmium(II) does notinfluence the percentage extraction of copper(II), relatively.

This study aimed to determine the optimum condition on the extraction process of mercury ions with the variables of study on the ratio of membrane phase volume and internal phase volume (Mp:Ip) and the extraction time which will provide the greatest percent extraction. Sample used in this study was an artificial sample containing Hg(II) ions with a concentration of 10 mg/L. Hg(II) ions will be distributed into internal phase through membrane phase formed from a mixture of surfactants, kerosene and chelating compounds. Concentration of mercury ions remained in the samples was analyzed using a UV-VIS spectrophotometer at a wavelength of 490 nm with ditizon as a complex. The optimum condition was achieved at a volume ratio of membrane phase (Mp) with internal phase (Ip) of 2:2, and the extraction time was for 10 minutes, where percent extractions were 66.11% and 82.23%, respectively.

Demulsification Efficiency

Removal of phenol from aqueous solution by a new emulsion liquid membrane (ELM) system and its heat-induced demulsification have been investigated. The ELM consists of commercial kerosene as organic solvent, OP-4 as surfactant agent, hydrochloric acid as the stripping phase. Effect of different operating parameters such as internal phase concentration, surfactant concentration, stirring speed, PH value in external phase, volume ratio of membrane phase to internal phase and volume ratio of membrane phase to external phase were investigated for the removal of phenol from aqueous solution. At the optimum condition about 95.7% phenol is removed in less than 20min of contact time. The demulsification efficiency was investigated under different temperature and time and proved to be high at 80°C.

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.

The recycling of copper and nickel from metallurgical wastewater using emulsion liquid membrane (ELM) was studied. P507 (2-ethylhexyl phosphonic acid-2-ethylhexyl ester) and TBP (tributyl phosphate) were used as carriers for the extraction of copper and nickel by ELMs, respectively. The influence of four emulsion composition variables, namely, the internal phase volume fraction (ϕ), surfactant concentration (Wsurf), internal phase stripping acid concentration (Cio) and the carrier concentration (Cc), and the process variable treat ratio on the extraction efficiencies of copper or nickel were studied. Under the optimum conditions, 98% copper and nickel were recycled by using ELM. The results indicated that ELM extraction is a promising industrial application technology to retrieve valuable metals in low concentration metallurgical wastewater.

This study aimed to determine effect of Cu(II) ion toward percent extraction of Pb(II) ion using emulsion liquid membrane technique. Variation concentrations of Cu(II) added were 0, 50, 100, 150, 200 and 250 ppm with the initial concentration of Pb(II) was 245 ppm. This extraction used benzoyl acetone as a chelating agent.
