Popis: | Regarding supported liquid membrane (SLM), the mutual solubility of both the organic and aqueous phases has an influence on its stability. Investigation into causes of mutual solubility is very important to prevent instability of the system. This work focuses on the influence of water pH as regards the solubility and stability of SLM. For the organic phase, ionic-liquid extractant viz. Aliquat 336, combining with various organic solvents, was used. As for the aqueous phase, acidic, neutral and basic water was prepared. The solubility of the liquid-liquid ternary systems (adjusted pH water + Aliquat 336 + organic solvents) was carried out at T = 303.2 K and atmospheric pressure. Tie-line data of the ternary systems were also determined. Good correlation of tie-line data from the NRTL model and experiments was confirmed and validated by the root-mean square deviation values which were |
