Supported liquid membrane (SLM) was prepared by reacting host material with carrier compounds. Carrier compound was Polyethylene Glycol-400 (PEG-400) that have been used with the variation of concentration 0, 2, 4, and 6%. The effect of its variations in SLM was characterized by FTIR and the performance was examined by transporting feed solution Pb(NO 3 ) 2 with variation 1, 5, 10, 15, and 25 ppm for 3 hours in pH 3. FTIR spectra depicted that the increasing concentration of PEG would arise the intensity of typical PEG's functional groups such as -OH, C-O-C, and CH 2 -CH 2 sp3. The optimum transport Pb(II) was achieved by SLM with 6% PEG. Variation of feed solution concentration showed the main effect in SLM activity. The higher of feed solution concentration would decrease of transport activity. The % extract and % recovery 1 ppm was higher than 25 ppm with 72,5% and 70,27% than 6,1% and 3,59%, respectively.

“…There is an urgent need for a method to remove heavy metals from sewage to meet the growing environmental quality requirements [7]. Common methods for treating heavy metal ion pollutants in wastewater include chemical precipitation, extraction, membrane separation, ion exchange, electrochemical and adsorption [8][9][10][11][12][13][14]. The adsorption method has gradually entered the researcher's line of sight because of its simple operation, safety, simple equipment, low cost, wide applicability and possible recyclability of the adsorbents [15].…”

The graphene oxide(GO)/polyacrylic acid(PAA) was prepared by in situ polymerization in graphene oxide lamellae, and crosslinked graphene oxide/polyacrylic acid complex(CLGO/PAA) was formed by esterification reaction between 1,4-butanediol and carboxylic acid of PAA at same time. The CLGO/PAA aerogel was prepared by freeze drying method. The CLGO/PAA aerogel has good stability and high saturated adsorption capacity for the adsorption of Pb(II) ions in water. The structure and properties of the CLGO/PAA aerogel were characterized by using x-ray diffractometry (XRD), field emission scanning electron microscopy (FESEM), infrared spectroscopy(FT-IR), and atomic absorption spectrometer(AAS), respectively. The results show that the prepared CLGO/PAA aerogel possess elliptical pore structure. In addition, the adsorption properties of the CLGO/PAA aerogel for Pb(II) in water were studied under different pH, different concentrations of Pb(II), contact time and number of adsorbent cycles. The results show that the adsorption amount of Pb(II) could reach to 640 mg g −1 at the initial concentration of Pb(II) was 500 mg l −1 , and the adsorption equilibrium could be reached after 60 min. The adsorption amount for Pb(II) was still 143 mg g −1 after 5 times cycle.

“…Solutions of D2EHPA in organic solvents are widely used as the liquid membranes for the removal, separation or concentration of metals. The transport of Pb(II) from neutral and weakly acidic solutions using D2EHPA-based emulsion [5], supported [6], hollow fiber [7] liquid membranes and polymeric inclusion membranes [8] is reported in the literature. The gradient of hydrogen ion concentration acts as the driving force for the transportation of metal ions in these systems.…”
