Polymer inclusion membrane based on cellulose triacetate (CTA) plasticized with 2-nitrophenyl octyl ether

Polimery 2015, No 2, 118


DOI: dx.doi.org/10.14314/polimery.2015.118

Summary

The article describes astructure of the polymer inclusion membrane (PIM) with cellulose triacetate (CTA) matrix and its use for the separation of chromium(III) ions from aqueous solutions. Di(2-ethylhexyl) phosphoric acid (D2EHPA) was used as a ion carrier. The efficiency of Cr(III) ions transport in the test system was dependent on the carrier concentration in the membrane. In periodic processes the performance of PIM system was stable, which indicates the possibility of using it for the selective separation of Cr(III) from amixture of Cr(III)/Cr(VI) ions.


Keywords: polymer inclusion membrane, cellulose triacetate, 2-nitrophenyl octyl ether, chromium, ion carriers
