Tao He, Composite hollow fiber membranes for ion separation and removal

Environmentally benign operation of chemical processes have attracted significant attention over the past decades. In removal of heavy metal ions from waste effluents, membrane technology has become increasingly attractive as a low-cost generic separation technique for environmental problems. Membrane processes compete with a variety of processes, such as chemical precipitation, metallic replacement, ion exchange, electrolysis, adsorption, flotation and biological approaches
