Abstract
In this paper, we describe the synthesis of magnesium aminoclay-iron oxide (MgAC-Fe3O4) hybrid composites for microalgae-harvesting application. MgAC-templated Fe3O4 nanoparticles (NPs) were synthesized in different ratios of MgAC and Fe3O4 NPs. The uniform distribution of Fe3O4 NPs in the MgAC matrix was confirmed by transmission electron microscopy (TEM). According to obtained X-ray diffraction (XRD) patterns, increased MgAC loading leads to decreased intensity of the composites’ (311) plane of Fe3O4 NPs. For harvesting of Chlorella sp. KR-1, Scenedesmus obliquus and mixed microalgae (Chlorella sp. KR-1/ Scenedesmus obliquus), the optimal pH was 4.0. At ...
