技術說明

一種氧化石墨烯-鐵複合薄膜之製備方法，用以解決習知方法所製得之氧化石墨烯-鐵複合薄膜置於水溶液內造成結構不穩定的問題。係包含以下步驟：齊備氧化石墨烯水溶液；將亞鐵離子鹽中鐵離子與氧化石墨烯水溶液中氧化石墨烯以1：5至1：7之重量比混合，以得到混合溶液；將混合溶液進行抽氣，以得到黑色薄膜；以及，將黑色薄膜進行烘乾，以得到氧化石墨烯-鐵複合薄膜。一種氧化石墨烯-鐵複合薄膜，包括複數氧化石墨烯層及鐵離子，鐵離子與各氧化石墨烯層之表面的羥基、環氧基、羰基及羧基相結合。一種氧化石墨烯-鐵複合薄膜用於去除廢水中汙染物質之用途。 Provided is a method for preparing a graphene oxide-ferrum composite film, to solve problems existing in the conventional methods that may not prepare graphene oxide film able to maintain stable structure thereof as soaking in the solution, comprising steps of preparing a graphene oxide solution; mixing a ferrous ion salt with the graphene oxide solution in a weight ratio of from 1:4 to 1:8, to obtain a mixed solution; pumping the mixed solution, to obtain a black film; and drying the black film to obtain the graphene oxide-ferrum composite film. A graphene oxide-ferrum composite film comprises a plurality of graphene oxide-ferrum composite film layers and ferrous ions. The ferrous ions are connected to hydroxyl group, epoxy group, carbonyl group, and carboxyl group existing on the surface of each graphene oxide-ferrum composite film layer. A use of graphene oxide-ferrum composite film for removing pollutants from wastewater.
