Abstract: IN THIS STUDY, A NOVEL BUOYANT COMPOSITE PHOTOCATALYST WITH PHOTOCATALYST AND ADSORBENT COMPONENTS IMMOBILIZED ON A BUOYANT SUBSTRATE WAS DEVELOPED AND STUDIED. THE PREPARATION METHOD WAS INVESTIGATED AND THE COMPOSITION OF THE MATERIAL WAS OPTIMIZED. VARIOUS CHARACTERIZATION ANALYSES AND REMOVAL OF PHENOL FROM AQUEOUS SOLUTIONS WERE CONDUCTED TO EXAMINE THE PROPERTY AND PERFORMANCE OF THE DEVELOPED MATERIAL AS WELL AS THE FUNCTIONS AND WORKING MECHANISMS OF THE DIFFERENT COMPONENTS IN THE COMPOSITE PHOTOCATALYST. IT WAS FOUND THAT THE COMPOSITE MATERIAL WITH BOTH ADSORPTION AND PHOTOCATALYSIS COMPONENTS SHOWED A NUMBER OF UNIQUE ADVANTAGES OVER THE INDIVIDUAL COMPONENTS AND ESPECIALLY DISPLAYED SOME DISTINCTIVE SYNERGISTIC EFFECT IN THE REMOVAL OF PHENOL. THE STUDY ALSO SHOWED THAT THE PROPER COMBINATION OF THE ADSORBENT AND PHOTOCATALYST COMPONENTS IN THE COMPOSITE PHOTOCATALYST (BOTH RATIO AND CONFIGURATION) WAS IMPORTANT AND HAD A LARGE IMPACT ON THE PROPERTY AND PERFORMANCE OF THE
