摘要
双极膜是一种新型的离子交换复合膜,因其具有操作简单、效率高、污染排放少等诸多优点,已在资源回收、污染控制与化学工程等诸多领域得到广泛应用,相关的研究也日趋活跃.目前国内外双极膜研究的热点是提高双极膜中间界面层的水解离效率,降低跨膜电压并拓展其应用领域.本文对近年来国内外有关双极膜的改性、应用及发展动向进行了介绍,并对双极膜的研究进行了展望.
Bipolar membrane （BPM） comprises an important area of membrane research. BPM technology has been applied in industries for resource recovery, pollutant control and chemical processing with a simple process, high efficiency, and low waste disposal. How to promote water splitting at the interlayer of a BPM, lower the trans-membrane voltage drop （IR drop, here, I. electric current~ R. membrane impedance） and extend the application field was the focus of the BPM research. Recently, BPM research attracts many researchers and becomes a very active field. In this paper, research progress in the modification of BPM in recent years is summarized. The applications including chemical engineering, environmental pollution control, resource recovery, food and medical industry and so on are introduced in details. Moreover, the prospect and challenge to the BPM research are also discussed.
