英文摘要 | Mg(OH)(2) nanoparticles were successfully prepared and incorporated in the poly(vinylidene fluoride) (PVDF) membranes to enhance the hydrophilicity, anti-fouling, and dye treatment capacity. The products were characterized by multiple techniques including scanning electron microscopy, size distribution by intensity, Fourier transform infrared, powder X-ray diffraction, the Brunauer-Emmett-Teller surface area, and energy dispersive spectrometer elemental mapping. Mg(OH)(2) nanoparticles possessed uniform particle sizes and were homogeneously dispersed in the PVDF matrix with less aggregation. The incorporation of Mg(OH)(2) nanoparticles into PVDF composite membranes caused a decrease in the contact angle and great improvements in the pure water flux from 252 to 471 L m(-2) h(-1) and bovine serum albumin rejection from 40% to 80% at the same time. In addition, the composite membranes had a significant increase in adsorption of cationic dyes methylene blue from 4.6 to 8.3 mu g cm(-1) and rejection from 11% to 21% when Mg(OH)(2) nanoparticles were added from 0 to 1.5 wt.% due to the good adsorption for dyes of Mg(OH)(2) nanoparticles. The removal rate of anionic dye Congo red increased from 72% to 98% and rejection increased from 13% to 80% when Mg(OH)(2) nanoparticles were added from 0 to 1.5 wt.%. This study provides information on application potential of Mg(OH)(2) nanoparticles incorporated in membranes for treating dye wastewater. |
