Sugar is released during biomass hydrolysis together with unwanted inhibitory compounds such as acetic acid, furfural and hydromethylfurfural. The extraction of particular sugar prior to fermentation process is needed in order to increase the yield of biofuel generated from biomass resources. In the current study, glucose was extracted from the aqueous solution using supported liquid membrane (SLM) system. Polyethersulfone (PES) flat sheet membrane support was fabricated using 15 wt.% PES, 42.5 wt.% DMAc and 42.5 wt.% PEG 200. Liquid membrane was formulated using 2-ethyl hexanol and methyl cholate as solvent and carrier, respectively. The effect of several parameters involved in SLM system such as type of diluent and flowrate of feed and stripping phase on the extraction performance of glucose were studied. About 52.77% of glucose was successfully extracted from aqueous solution using SLM system with 0.01M of methyl cholate in 2-ethyl hexanol. Using simulated biomass hydrolysate solution, almost 54.55% of glucose and 51.08% of xylose were successfully extracted using the SLM system.

Supported liquid membrane (SLM) is one of the potential extraction methods for the treatment of wastewater containing various toxic heavy metal ions. Advantageously, this process offers simultaneous removal and recovery, as well as low energy consumption and operational cost. In this study, the prediction of nickel removal was investigated using a diffusion model developed through MATLAB.

The transport of germanium from an aqueous solution containing oxalic acid was studied using a flat sheet supported liquid membrane (FSSLM) system. Cyanex 923 immobilized in a polytetrafluoroethylene membrane was employed as a carrier. The solution chemistry and related diagrams were applied to study the transport of germanium. The effectual parameters such as oxalic acid, the carrier, and strip reagent concentrations were evaluated in this study. Based on the results, the oxalic acid concentration of 0.075 mol/L and the carrier concentration of 20 %v/v were the condition in which the efficient germanium transport occurred. Among strip reagents tested, NaOH had the best efficiency to transport germanium through the supported liquid membrane system. Furthermore, the permeation model was obtained to calculate the mass transfer resistances. According to the results, the values of 1 and 1345 s/cm were evaluated for Δm and Δf, respectively. The model curve showed that the P value reached a steady state at higher concentrations of the carrier because the viscosity governed the transport phenomenon.
