Özet
The transport behavior of Hg2+ from aqueous solution through a flat-sheet-supported liquid membrane (SLM) has been investigated by using of calix[4]arene derivatives (1and 2) as carriers and Celgrad 2400 and 2500 as the solid support. The effect of solvent type and anions such as chloride and nitrate ions on the transport of Hg2+ was examined. Danesi mass transfer model was used to calculate the permeability coefficients for each parameter studied. The highest values of permeability were obtained with 2-nitrophenyl ethyl ether (NPOE) solvent and the influence was found to be in the order, NPOE > chloroform > xylene. The transport efficiency on the supported liquid membrane was dependent on the type of carrier, its characteristics, and the type of the solvent.
