a comprehensive study pertaining to the emulsion liquid membrane (elm) extraction process to enrich dilute aqueous solutions of silver salt is presented. the study has highlighted the importance and influence of membrane composition for maximizing the extraction of ag+ ions. the liquid membrane was made up of cyanex-302 as an extractant and the industrial solvent mainly consists of paraffinic a...

The ionic liquid 1-(3-amino-3-oxopropyl)-3-vinylimidazolium bis(trifluoromethylsulfonyl)amide ([PIVM][TFSA]) was synthesized and applied in the electrolyte of Li/LiNi0.6Co0.2Mn0.2O2 lithium ion batteries. thermostability this pure investigated to provide a wide range from -50 ℃ 200 ℃. physicochemical properties binary mixtures with DMC EMC were measured at different temperatures mole fractions....

artificial neural networks (anns) are computer techniques that attempt to simulate the functionality and decision-making processes of the human brain. in the past few decades, artificial neural networks (anns) have been extensively used in a wide range of engineering applications. there are only a few applications in liquid membrane process. the objective of this research was to develop artific...

Shlyonsky V. Ion permeability of artificial membranes evaluated by diffusion potential and electrical resistance measurements. Adv Physiol Educ 37: 392–400, 2013; doi:10.1152/advan.00068.2013.—In the present article, a novel model of artificial membranes that provides efficient assistance in teaching the origins of diffusion potentials is proposed. These membranes are made of polycarbonate filt...

In the present study, a new gas diffusion electrode (GDE) (based on Pt/Nafion membrane) is fabricated. The electrochemical results show that the new GDE has the highest electrochemical activity toward the oxygen reduction reaction (ORR) among the three electrodes. The SEM and XRD findings show that a platinum layer can be attached to Nafion membrane closely and firmly with a strong peak corresp...

In the present article, a novel model of artificial membranes that provides efficient assistance in teaching the origins of diffusion potentials is proposed. These membranes are made of polycarbonate filters fixed to 12-mm plastic rings and then saturated with a mixture of creosol and n-decane. The electrical resistance and potential difference across these membranes can be easily measured usin...

Surfactants (surface active agents) are substances which incorporate a hydrophobic non-polar and a hydrophilic polar group, and have the tendency to accumulate at the phase boundary. This feature causes the wide application of surfactants. In 2012, the world surfactant market amounted to 27,040 million USD, and with average annual increase of 6.18 %, this amount in 2017 is estimated at 36,518 m...

ecotoxicity of rhodium (rh) from the model of mining waste water side stream was examinedin this paper. rh was extracted from the model of the mining waste water using an emulsion liquid membrane(elm). the extractions were done at ph of 1.87 and ph 2.92 and 41.6 % and 46.2 % of rh was extractedrespectively. the side streams of ph of 1.87 and ph 2.92 after the extractions were examined for ecoto...
