| Résumé : |
The transport of cationic dye from an aqueous feed solution through a flat-type supported liquid membrane containing di-(2-ethylhexyl)phosphoric acid as a carrier was studied. The influence of pH on the source phase, the effect of the concentration of the receiving phase, the stirring speed, the effect of the initial dye concentration, the feed-to-strip ratio and the influence of the support characteristics were studied. A polytetrafluoroethylene membrane with a 1.0-µm pore size was found to have more permeability than that with a pore size of 0.5 µm. The results indicated that the aqueous feed solution at an alkaline pH has high permeability. The initial feed phase dye can be completely extracted and stripped with a stripping solution within 7 h. |
