Desalination of seawater using various polymer inclusion membranes was carried out. Polymer inclusion membrane (PIM) is known to have the highest stability, able to overcome liquid membrane instability and was placed in between two phases: the source phase is seawater and the receiving phase is the micro-filtered water. Determination of salinity levels in the feed phase and the receiving phase was carried out using a salinity meter, while membrane characterization was done using FTIR and SEM techniques. Polyvinyl chloride (PVC) based PIM membranes were prepared using different single and mixed synergtic carriers ratio of 1:1 viz. dibutyl ether, methyltrioctylammonium chloride (Aliquat 336), di-(2-ethylhexyl)-phosphate (D2EHPA), thenoyl trifluoroacetone (HTTA), tributyl phosphate (TBP) and eugenol (PE). The results showed the salinity value for single HTTA carriers had a greater salinity value in comparison to mixed carriers (HTTA:TBP; HTTA:Aliquat; D2EHPA:TBP; and D2EHPA:Aliquat) gave different salinity value towards the desalination process.

Research on recovery of Cu (II) and Cr (VI) from electroplating liquid waste has been carried out using a Polymer Inclusion Membrane (PIM). PIM has a high stability to overcome the weakness of liquid membrane instability. The PIM membrane was placed between two phases namely the feed phase as a metal source of Cu (II) from electroplating waste with pH 3 and the receiving phase which is HNO3 solution with pH 1 and pH 4.4 in the feed phase and pH 6.3 in the receiving phase with NaCl 2 N for metal Cr (VI). Recovery efficiency is known by determining the concentration of Cu (II) and Cr (VI) in the feed and receiving phases using AAS, while the membrane characterization were carried out using FTIR, SEM and UV-vis spectroscopy. The resulting PIM membrane has properties of thin, clear and flexible. AAS data showed that the percentage of PIM transport with stirring for 24 hours performed the highest percentage of Cu (II) metal transport from feed phase of 83.41% and transport in the receiving phase of 72.56%. While the percentage of optimum Cr (VI) transport was 97.8% in the feed phase and 76.5% in the receiving phase. The results of membrane characterization using FTIR and UV spectroscopy showed that the PIM membrane was quite stable. While the results of SEM show that there were no pores in the membrane so that the transport occurs by diffusion through the intermediate of the carrier compound. Keywords: electroplating waste; liquid membrane; PIM

The study on the transport behavior of Cr(III), Cd(II), Pb(II), and Ag(I) through bulk liquid membrane using p-tert-butylcalix[4]arene-tetradiethylacetamide as ions carrier has been conducted. The aims of this work are to determine the optimum condition, efficiency, and transport selectivity of the carriers for those ions. Both optimum condition and transport efficiency were obtained by determination of the concentration of transported ions with variation of the source phase pH, ion carrier concentration, the nature of decomplexant agent in the receiving phase, and transport time. The transport selectivity of the ion carrier was obtained from the ions competition transport experiments. The amount of Cr(III), Pb(II), Cd(II), and Ag(I) transported across liquid membrane were 11.6, 25.5, 39.5, and 42.1% respectively. The ion carrier is selective for Cd(II), Pb(II), Ag(I), and strongly depends on the nature of decomplexant agent as well as transport mechanism. The remarkable selectivity was shown by the ion carrier to Ag(I) when the transport process was carry out under high concentration of acid in the source phase.   Keywords: transport, p-tert-butylcalix[4]arene-tetradiethylacetamide, efficiency, selectivity, bulk liquid membrane, heavy metals

Phenol is considered a pollutant in the environment due to its toxicity and carcinogenic effect. Supported liquid membrane (SLM) is a good and promising technology for the removal of phenol from wastewater because it provides maximum driving force for the separation of targeted solute and simultaneous extraction and stripping process which lead to excellent separation. In this research, kerosene and palm oil liquid membranes were used as liquid membrane phase, aqueous phenol as the feed phase and aqueous sodium hydroxide as the stripping phase. Several factors such as feed phase pH, feed phase flow rate and concentration of stripping phase were studied.  The results show that the best extraction performance can achieve 35% at pH 4 of feed phase, 150 ml/min feed flow rate and 1.0 M of stripping phase concentration. The result was used to determine the probability of using palm oil as a liquid membrane. In the determination of the potential of using palm oil as the membrane phase, the results show that an equal portion of palm oil and kerosene mixture performed the best extraction with 43% efficiency.

AbstractStudies on liquid-liquid extraction and bulk liquid membrane (BLM) technique-based metal ion separation by a previously published Pb2+-selective acridono-18-crown-6 ether selector molecule were performed. The effects of the stirring speed, the quality of apolar organic membrane, the counterions of Pb2+, the pH of the aqueous phase, the concentration of the source phase, the concentration of the carrier in the BLM and the temperature on the Pb2+-separation were investigated. Moreover, the effects of the competitive inhibition due to the presence of Ag+, Ca2+, Co2+, Cu2+, K+, Mg2+, Na+ and Zn2+ as competing ions in a multicomponent aqueous source phase of different ion-concentrations were also studied. After a proper dilution of the multicomponent aqueous source phase, excellent Pb2+-selectivity was achieved without a significant reduction in the efficiency compared to the liquid membrane transport of single-component systems. Based on the BLM-cell studies the applied selector molecule proved to be suitable for the development of liquid membrane-based Pb2+-selective separation methods, which can be greatly aided by the analysis of the effects on the separation and by the optimization of the parameters of the process discussed here.
