The increasing numbers of product containing nanosilver have raised a great concern about their possible impact in the environment especially in the ionic form which leads to the toxicity problem when the association occurs with the organism cells. Therefore, the main focus of this study was to investigate several parameters influencing the recovery of ionized nanosilver from wash water using emulsion liquid membrane (ELM) process. This process involves three phases dispersion system including external, membrane and internal phase. The membrane phase was prepared by dissolving bis [2, 4, 4-trimethylpentyl] monothiophosphinic acid (Cyanex 302) as a carrier and Sorbitan Monooleate (Span 80) as a surfactant in kerosene as a diluent. Thiourea in Sulfuric acid (H2SO4) was used as a stripping agent in the internal phase. The important parameters such as extraction time, carrier and stripping agent concentrations were investigated. All experiments were conducted in batch system. The concentration of the ionized nanosilver was measured using Atomic Absorption Spectrometry (AAS). The result demonstrated that almost 100% of silver ion was extracted with 91% have been recovered within 5 minute of extraction time using 0.005 M Cyanex 302 and 1.0 M Thiourea in 1.5 M H2SO4. Hence, ELM was proven to be a very promising technique for the simultaneous extraction and recovery of ionized nanosilver from wash water.

Palladium is a rare precious metal with unique physical properties that are used in diverse industrial applications and in jewellery. Due to its economic value and its limited natural resources, palladium recovery from secondary resources has assumed a great significance. Therefore, this study investigated the possibility of using Emulsion Liquid Membrane (ELM) process for the extraction of palladium from simulated wastewater. The experiment was conducted using a mixer-settler in a batch system using 0.1 M Cyanex 302 in kerosene as a new carrier for palladium and 1.0 M Thiourea in 1.0 M H2SO4as a stripping agent. The effect towards membrane stability of different parameter such as surfactant concentration, emulsifying time and agitation speed has been attempted. The results show that at favourable condition of 2% w/v of span 80, 3 minutes emulsifying time, and 200 rpm agitation speed, 94% of palladium was extracted. Hence, ELM is proven to be a very promising technique for the extraction of palladium from wastewater.

Although textile dyes is basically available in very low concentration (10-200 ppm); it should be removed due to the toxicity to human body and environment. Among the existing methods, emulsion liquid membrane (ELM) is a promising method by providing high interfacial area and the ability to remove a very low concentration of the solute. The optimal emulsions were produced using commercially supplied homogeniser. Initially, methylene blue in simulated wastewater was extracted using a Taylor-Couette column. Methylene blue concentration was determined using spectrophotometer. Complete extraction was performed in the designed column. The research obtained optimal extraction efficiency of about 99% at external phase pH of 10, carrier concentration of 9 wt. %, HCl concentration of 0.5 M, initial feed concentration of 20 ppm, volume ratio of emulsion to feed phase of 1:5, extraction time of 5 min, and extraction speed of 600 rpm.
