Abstract

Environmental pollution caused by the presence of heavy metal ion from growing industrialization or from leaching is increasing area of concern. There are several area of water purifications but among them adsorption on the functionalized polymer fibers is efficient and cost-effective method. Polyacrylonitrile (PAN) is exciting polymer due to the presence of excessive functional group which can be easily transformed for metal ion adsorption. PAN can be easily electrospun to prepare nanofiber that have higher surface area leading to better metal ion removal. Composite PAN fiber is yet another type of polymer covered in this review for waste water treatment.

가속화되는 산업화로 인해 중금속 이온의 침출이 환경문제로 떠오르고 있다. 수질 정화를 위한 몇 가지 방법 중 기능성 고분자 섬유를 이용한 흡착은 효율적이며 경제적이라는 장점이 있다. 특히, 폴리아크릴로나이트릴(polyacrylonitrile, PAN)은 금속 이온을 흡착할 수 있는 작용기가 많아 관심을 끌고 있다. PAN은 쉽게 전기방사를 통해 고분자 나노 섬유화될 수 있으며 높은 표면적을 가질 수 있다. 본 총설에서 다룰 복합 PAN 섬유는 폐수 처리를 위한 또 다른 유형의 고분자이다.
