摘要:

當(dāng)前，工業(yè)制造過程中產(chǎn)生的含有有機(jī)污染物和有毒金屬離子的工業(yè)廢水對(duì)環(huán)境的污染越來越嚴(yán)重。而且金屬離子和有機(jī)物在水中不能自發(fā)降解，這對(duì)人類的生命健康構(gòu)成巨大的威脅。與此同時(shí)，針對(duì)水體凈化和污染物去除的研究也已經(jīng)取得了豐碩的成果。靜電紡絲納米纖維由于其可調(diào)控的纖維直徑、高孔隙率以及高比表面積在水凈化領(lǐng)域具有獨(dú)特優(yōu)勢(shì)，引起了廣泛的研究興趣。綜述了有機(jī)�矡o機(jī)雜化靜電紡絲納米纖維膜材料近年來在污染物吸附、抗菌、光催化及超疏水等水凈化領(lǐng)域的應(yīng)用研究進(jìn)展，闡明了各種有機(jī)-機(jī)雜化納米纖維膜對(duì)污水凈化的優(yōu)勢(shì)和效果等，并對(duì)其在未來水凈化方面的發(fā)展趨勢(shì)進(jìn)行了展望。

Abstract:

Contamination of water by organic pollutants, bacteria, and toxic metal ions generated from industrial processes is an urgent concern which must be addressed. These organic pollutants and metal ions cannot be digested, naturally. As a result, a great deal of research work in the removal of toxic pollutants from contaminated water has been carried out and some promising results have been achieved. Electrospun nanofibers, especially organic�瞚norganic hybrid nanofibers, have a unique advantage in water purification due to their adjustable fiber diameter, high porosity, high specific area, and high functionalizability, which raises researchers�� extensive interests. Here, we review the progress of organic�瞚norganic hybrid nanofibrous membranes in terms of pollutant adsorption, bacterial removal, and photo�瞕egradation for water purification. The advantages and efficiencies of various organic�瞚norganic hybrid nanofibrous membranes were demonstrated and elucidated, systematically. Future prospects in the developing trends of such membranes for wastewater treatment have been explored.
