Abstract: The present disclosure relates to a floating type adsorbent for removal of phosphate that can effectively remove phosphate from aqueous phase through reaction between an amine function attached on the surface of a sponge and phosphate. This adsorbent can be regenerated by desorbing the adsorbed phosphate, a method for fabricating same and a method for regeneration the floating type adsorbent for removal of phosphate. The floating type adsorbent for removal of phosphate according to the present disclosure is fabricated by immersing a sponge in a mixture solution of an amine precursor and anhydrous toluene to form an amine function on the surface of the sponge. The amine precursor may be 3-aminopropyltriethoxysilane (APTES) and the APTES and the anhydrous toluene may be mixed at a volume ratio of 0.5-1:1.
