High molecular weight amines, quaternary salts etc. have the potential of removing heavy metal ions including the toxic ones at low concentrations. In the present work an attempt has been made to extract Cr(VI) through emulsion liquid surfactant membrane (or, emulsion liquid membrane-ELM) from it’s acidic solution using alamine-336 and caustic soda as extractant and striping reagents respective...

A study on the extraction of Acetaminophen (ACTP) which is also known as paracetamol, from aqueous solution by emulsion liquid membrane process using Taylor-Couette Column (TCC) was investigated. An ELM consists of three phase system which are the external, membrane and internal phases. The external phase containing the ACTP aqueous solution to be treated. Basically, the internal and membrane p...

Extraction of lactic acid by emulsion liquid membrane technology (ELM) using n-trioctyl amine (TOA) in n-heptane as carrier within the organic membrane along with sodium carbonate as acceptor phase was optimized by using response surface methodology (RSM). A three level Box-Behnken design was employed for experimental design, analysis of the results and to depict the combined effect of five ind...

Emulsion Liquid Membrane (ELM) is an emerging technology that removes contaminants from water and industrial wastewater. This study investigated the stability extraction efficiency of ELM for removal Chlorpyrifos Pesticide (CP) The was studied in terms emulsion breakage. proposed included n-hexane as a diluent, span-80 surfactant, hydrochloric acid (HCl) stripping agent. Parameters such mixing ...

Emulsion liquid membrane (ELM) has been widely studied as an alternative method for amine absorption technology in the removal of acid gases such carbon dioxide (CO2) and hydrogen sulphide (H2S). However, searching stable ELM formulation with enhanced CO2 remains challenge. Therefore, this study, aqueous solution containing a mixture methyl diethanolamine (MDEA) 2-amino-2-methyl-1-propanol (AMP...

A statistical programme using Box-Behnken design, which applies a response optimization algorithm, was used to calculate and optimize simultaneously the lactic acid extraction by emulsion liquid membrane (ELM) in a mixed flow reactor. A 3-level Box-Behnken design with seven variables i.e. lactic acid concentration, internal reagent concentration, Alamine 336 fraction in oleyl alcohol, stirring ...

This work aims to study the recovery of copper from ammoniacal aqueous solutions using hydrophobic propylene membrane contactors. The hydroxyoxime LIX 84-I and the β-diketone LIX 54 (both from Cognis) were used as extractants. The results obtained showed that practically all the copper content was removed from the ammoniacal feed solutions. The recovery of copper reached nearly 100% in several ...

The extraction efficiency of hexavalent chromium, Cr(VI), from water has been investigated using a vegetable oil based emulsion liquid membrane (ELM) technique. The main purpose of this study was to create a novel ELM formulation by choosing a more environmentally friendly and non-toxic diluent such as palm oil. The membrane phase so formulated includes the mobile carrier tri-n-octylmethylammon...
