氯苯那敏(chlorpheniramine)為一種過敏性用藥，常被用於舒緩過敏性鼻炎或蕁麻疹的症狀。然而，氯苯那敏於攝取後，並不容易完全被人體代謝，因此可能會隨著人體的排泄物而進入廢水中，並且被廢水處理廠所使用的消毒劑(例如：氯及臭氧)氧化而轉變為具有致癌性的亞硝胺，因此該如何去除水中的氯苯那敏，進而防止氯苯那敏轉變為致癌物質，確實為一個刻不容緩的課題。 Chlorpheniramine is an allergic drug that is often used to relieve symptoms of allergic rhinitis or urticaria. However, chlorpheniramine is not easily metabolized by the body after ingestion, so it may enter the wastewater with the body's excretion and be oxidized by disinfectants (such as chlorine and ozone) used in wastewater treatment plants.

綜合上述，本發明之含鐵氧化石墨烯複合物的製造方法，係利用四氧化三鐵與氧化石墨烯製作出含鐵氧化石墨烯複合物，該含鐵氧化石墨烯複合物可以有效吸附氯苯那敏，藉此可以處理含有氯苯那敏之污水。 In summary, the method for producing the iron-containing graphene oxide composite of the present invention comprises using a ferroferric oxide and graphene oxide to produce a ferro-containing graphene oxide composite, and the iron-containing graphene oxide composite can effectively adsorb chlorobenzene. Namin, by this, can treat sewage containing chlorpheniramine.
再者，藉由以含鐵氧化石墨烯複合物吸附水中的氯苯那敏，可以防止氯苯那敏於水中轉變為致癌物質，達成提升生物體健康的功效。 Furthermore, by adsorbing chlorpheniramine in water with an iron-containing graphene oxide composite, chlorpheniramine can be prevented from being converted into a carcinogen in water, thereby achieving an effect of improving the health of the living body.
雖然本發明已利用上述較佳實施例揭示，然其並非用以限定本發明，任何熟習此技藝者在不脫離本發明之精神和範圍之內，相對上述實施例進行各種更動與修改仍屬本發明所保護之技術範疇，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims.
