Abstract:

With the rapid development of population growth and industrialization,a large number of toxic and harmful substances are directly discharged without treatment,causing serious pollution to the water environment.Adsorption method is widely used in the field of water treatment because of its easy operation and high efficiency,so the development of efficient and inexpensive adsorbents has become the focus of current research.Magnesium oxide fiber not only inherits the characteristics of magnesium oxide,which is high temperature resistant,non⁃toxic and environmentally friendly,but also has the high specific surface area and good self⁃supporting properties of fiber materials,which is a highly potential adsorbent material.By compounding magnesium oxide with other materials,magnesium oxide⁃based composite fibers are obtained,which can further enrich the active sites of the fibers and improve the mechanical properties of magnesium oxide fibers.The common preparation methods of magnesium oxide fibers and their composite fibers,i.e.,centrifugal spinning method,electrostatic spinning method,template method,etc.,were systematically introduced.The current status of the development of magnesium oxide fibers and magnesium oxide⁃based composite fibers both at home and abroad in recent years was summarized,with a focus on the research progress and application direction of the adsorption field.Finally,the problems that need to be solved and the challenges that need to be faced for the development of magnesium oxide fibers and their composite fibers were pointed out,based on which was prospected.

Key words: magnesium oxide fiber, magnesium oxide?based composite fiber, fiber preparation, adsorption
