Pertraction

Application of the liquid emulsion membrane (LEM) technology to the industrial scale is hindered by the challenges imposed by stability of the emulsion during the transfer of the solute (pertraction). One of the important factors which leads to the instability is swelling. Emulsion undergoes swellin

The transport of iodine through a bulk liquid membrane containing kerosene as solvent and alkaline sodium sulfite solution as receiving phase in a bench scale system was studied. It was found that the pH of feed solution has a major effect on the extraction rate. On the other hand, the concentration

A liquid/liquid extraction process mediated by membrane contactors containing fixed recognition sites is being proposed for isomer discrimination. Cyclodextrins (CDs) are able to form inclusion complex of different stability with organic molecules depending on their shape and size. In this paper, we

Transport of phenylalanine (Phe) through a supported liquid membrane (SLM) containing di-(2-ethylhexyl) phosphoric acid (DEHPA) as carrier in a spiral-channel module was studied. The value of the molar flux of Phe through SLM increases with the velocity of the feed phase in the channel. However, soo

Extraction of gold (III) ions from aqueous solutions by two types of emulsifier using the emulsion liquid membrane technique was investigated. Experimental results for the batch extraction of gold (III) ions using a surfactant liquid membrane technique are presented. A comparison was made between a

In this paper the multistage membrane pertraction (simultaneous extraction and reextraction) of phenol with linear monoalkyl cyclohexane (lMACH) as a carrier and sodium hydroxide solution as a strip, in laboratory scaled pertractors with polysulphone hollow-fiber membranes, was investigated. Two typ

The co-transport of silver from nitric acid solutions across a bulk liquid membrane (BLM) in a HF contactor and across a layered BLM with a new carrier octylphenylmethane-sulfide (MF18) have been studied. The transport rate of silver through a BLM containing the MF18 in the HF contactor is much lowe
