Ibuprofen (IBP), 2-[4-(2-methylpropyl) phenyl] propanoic acid belongs to the category of non-steroidal anti-inflammatory drugs which are widely used for the treatment of musculature pain, inflammatory disorders, fever, migraine, and tooth aches [1]. It has been reported that several kilotons of IBP are produced annually in the world, part of which being rejected to the effluents and excreted by patients [2]. IBP is not biodegradable in the municipal wastewater treatment plants. Thus, several techniques have been proposed for the removal or efficient and low cost [4]. Bismuth tungstate (Bi2WO6), a member of the Aurivillius oxide family with the general formula of Bi2An−1BnO3n+3 (A=Ca, Sr, Ba, Pb, Bi, Na, K and B =Ti, Nb, Ta, Mo, W, Fe) is an ideal candidate for the visible-light-driven photocatalytic material [5]. However, it is not easy to reuse and recycle photocatalysts due to the difficulty of its recovery from aqueous media. In fact, the reusability of photocatalysts is a major concern of industrial applications. The use of magnetic- photocatalyst nanomaterials can be promising as they both allow easy recovery by an external magnetic field and exhibit the advantages of high degradation efficiency. In this study, a simple synthesis approach was used to prepare magnetite nanosphere with hydrophilic surface in polyol media.
