Synthesis and absorption organics of biomorphic hollow fibers Al₂O₃ and acrylic ester‐based crosslinked resin composite

Biomorphic hollow fibers Al₂O₃ was prepared by impregnation–calcination method using cotton as a template. The as‐prepared biomorphic Al₂O₃ was modified by vinyl triethoxysilane (A151) and biomorphic Al₂O₃ became hydrophobic. The high‐oil‐absorption resin composite were synthesized by suspension polymerization with butyl methacrylate (BMA), butyl acrylate (BA), and styrene (St) as the monomers. The samples were characterized by X‐ray diffraction, scanning electron microscope, and thermogravimetric‐differential thermal analysis (TG‐DTA). The composite resin showed a tetrachloromethane absorption capacity of 44.57 g/g and an excellent thermostability. After 10 cycles of regeneration, the composites still showed high absorption capacity for organics without significant quality loss. POLYM.
