摘要：

In this article, a novel poly-(acrylic acid-acrylonitrile) (PAA-AN)/filter paper composite membrane with pH-sensitivity was developed. The membrane was composed of three layers. The top and bottom layers were made of PAA-AN copolymer, while the middle layer was filter paper. The filter paper was used to enhance the strength of the membrane. The PAA-AN/filter paper membrane showed evident pH sensitivity and pH reversibility as the pH value changed between 2.0 and 9.5. With the increase of the PAA-AN copolymer amount in the composite membrane, the pH sensitivity increased. The Cu (II) ion-exchange experiment indicated that the membrane could bind metal ions and could be used as ion-exchange membrane to purify water. (C) 2010 Wiley Periodicals, Inc.
