Composite Membranes for Environmental Applications

摘要

The paper reports the synthesis and design of a membrane and its process for treatment of chromium, a major concern in tannery effluents. This study was focused on the preparation and characterization of PSf/titanium dioxide composite membranes for treatment of chromium solution. Different concentrated composite membranes were used for photocatalytic reduction of toxic chromium (Ⅵ) to non-toxic chromium (Ⅲ). X-ray diffraction study, transmission electron microscopy and Infrared spectral analysis were used to study the morphology and microstructure of the membranes. 100% reduction of 10 ppm chromium was observed .
