Liquid membrane

A short review of the different approaches to the mechanism of oscillations of electric potential difference between aqueous phases of liquid membrane oscillators is presented. More attention is paid to the mechanisms of oscillations proposed in our laboratory. For systems with cationic surfactant a

Supported-liquid membranes using four kinds of triethylene glycol (TEG) liquids were used for the VOC vapor removal from air. The supported-liquid membrane was a double-layer type, in which a liquid membrane was placed on a hydrophobic microporous membrane. This construction enabled the vacuum mode

It was previously suggested that liquid membrane oscillator systems might be used for the manufacture of taste sensors. The influence of substances responsible for taste belonging to bitterness, sweetness, sourness and saltiness on oscillation patterns of a liquid membrane oscillator with cationic s

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

Coupled transport of thiocyanate ions through a liquid membrane containing quaternary ammonium chloride salts in chloroform was examined. The influences of the carrier type in the membrane phase on the coupled transport of thiocyanate ions were investigated. The kinetics of the coupled transport wer

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

The liquid membrane transport of some biogenic amines (n-buthylamine, hexylamine) and aromatic amino acids methylesters by p-tert-butylcalix[n]arenes (n = 6.8) were investigated. The transport driving force was the pH gradient between the source and the receiving phases. The complexation properties

During the last two decades, an increased interest has been shown in trace elements in water. Metals trace play an important part in the natural geochemical cycles in water. The natural cycles are also affected by metals, particularly in the industrialised part of the world. The requirement for a wo
