    • The present invention relates to a barium hexaferrite nanofiber filter and a method for removing heavy metals using the same and, more specifically, to a method for separating, from aqueous media, magnetite having arsenic adsorbed thereto using barium hexaferrite nanofiber which shows the highest level of saturable magnetism of nanofibers. The barium hexaferrite nanofiber according to the present invention can separate magnetite particles completely from aqueous media owing to high magnetism, and can have high possibility of commercialization as the barium hexaferrite nanofiber can be woven in the shape of a filter and a continuous process method can be introduced. In addition, the barium hexaferrite nanofiber can be used practically in a water treatment site and thus can be supplied at low costs to some developing countries that have serious arsenic intoxication problems, as the barium hexaferrite nanofiber is easy to synthesize, and material costs and production costs are very low.
    • 本发明涉及六硼酸钡纳米纤维过滤器及使用其的重金属的除去方法,更具体地说,涉及一种从含水介质中分离具有砷吸附的磁铁矿的方法,所述方法显示出最高水平的六方铁纳米纤维 纳米纤维的饱和磁性。 根据本发明的六硼酸钡纳米纤维可以由于高磁性而将磁铁矿颗粒从水性介质中完全分离,并且由于六方晶系纳米纤维可以以过滤器的形状编织,并且连续的方法可以是 介绍。 此外,六亚铁酸钡纳米纤维实际上可以用于水处理场所,因此可以以低成本向具有严重砷中毒问题的发展中国家提供六硼酸钡纳米纤维易于合成的材料成本和生产 成本非常低。
