Supported hquid membrane

IPs, on the other hand, are uniquely suited for use as solvents for gas separations. Since they are non-voIatile, they cannot evaporate to cause contamination of the gas stream. This is important when selective solvents are used in conventional absorbers, or when they are used in supported Hquid membranes. For conventional absorbers, the ability to separate one gas from another depends entirely on the relative solubihties (ratio of Henry s law constants) of the gases. In addition, IPs are particularly promising for supported liquid membranes, because they have the potential to be incredibly stable. Supported liquid membranes that incorporate conventional liquids eventually deteriorate because the liquid slowly evaporates. Moreover, this finite evaporation rate limits how thin one can make the membrane. This... [Pg.90]

In Chapter 3, P. Dzygiel and P. Wieezorek survey the applications of supported hquid membranes and their modifications (gel, polymer inclusion SLMs, integrated systems) in separations of metal ions, organics, gases, and contaminants in wastewater, in biochemical and biomedical processing. Choices of membrane support material, carriers and solvents which improve the transport kinetics and membrane stabihty in SLM system are discussed. The use of novel calix-his-crown ether carriers shows the potential for large-scale utilization in the future. [Pg.10]

Parthasarathy and Buffle [55] have systematicaUy varied the chain length of a series of hpophihc carboxyhc acids in a supported hquid membrane with l,10-didecyldiaza-18-crown-6 as carrier. Chain lengths ranged from 10 to 18 carbons. Optimal Cu2+ transport was achieved with additives from 12 to 14 carbons in length, and lauric acid ( = 12) yielded the best results due to its decreased tendency to form precipitates with Cu2+.

The last example shows that it is also feasible to use SLMs to remove and recover efficiently radioactive metals from nuclear process effluent. By using a microporous hydrophobic polypropylene hoUow-fiber supported Hquid membrane (HFSLM) consisting of extractant, tri-w-butyl phosphate (TBP) as carrier diluted with w-dodecane, actinides such as uranium (U) and plutonium (Pu) were removed [188]. It was concluded after modeling and evaluation of the process conditions that it is possible to remove more than 99% of U(VI) and Pu(IV) from process effluent in the presence of fission products when stripping reagent 0.1 M hydroxylamine hydrochloride in...
