MANY FACTORIES, SUCH AS COAL CONVERSION, PETROLEUM REFINING, IRON AND STEEL, TEXTILES, DYES, RESINS, PLASTICS AND AGROCHEMICALS, DISCHARGE WASTEWATER CONTAINING PHENOLIC COMPOUNDS.THESE COMPOUNDS ARE HARMFUL TO HUMAN HEALTH, AND SUSPECTED TO BE CARCINOGENIC [1]. MANY TECHNIQUES INCLUDING PHYSICAL ADSORPTION [2], ELECTROCHEMICAL OXIDATION, BIODEGRADATION, CATALYTIC WET OXIDATION, AND FENTON REAGENT OXIDATION HAVE BEEN ADOPTED FOR THE REMOVAL OF PHENOLIC POLLUTANTS. THOUGH PRACTICABLE AND EFFECTIVE THESE METHODS ARE, THEY ALSO HAVE SOME DRAWBACKS, SUCH AS HIGH COST, INCOMPLETE REMOVAL, AND MORE TOXIC BYPRODUCTS THAN ORIGINAL POLLUTANTS [3]. IN VIEW OF SOLAR ENERGY UTILIZATION, THE DEVELOPMENT OF SEMICONDUCTOR PHOTOCATALYSTS FOR ORGANIC POLLUTANT DEGRADATION AND WATER SPLITTING IS A CHALLENGING AND INDISPENSABLE TOPIC OF MODERN RESEARCH [4]. IN THIS STUDY, SB/TIO2-FE3O4 NANOCATALYST WERE SUCCESSFULLY SYNTHESIZED AND CHARACTERIZED BY SEM, XRD, TEM AND USED TO REMOVE PHENOLS FROM AQUEOUS SOLUTION. IN THIS WORK THE INFLUENCE OF DIFFERENT PARAMETERS LIKE TEMPERATURE, PH, REACTION TIME, INITIAL PHENOLS AND SB CONCENTRATIONS WERE EXAMINED. RESULTS SHOW THAT THE DECREASE IN PH INCREASES THE REMOVAL EFFICIENCY. SO THAT IN PH=3 OVER 65% REMOVAL AND IN PH=11 ABOUT 51.5% REMOVAL IS OBSERVED. REMOVAL OF PHENOLS ELEVATED OVER TIME.DEGRADATION RATE WAS INCREASED BY REDUCING THE INITIAL CONCENTRATION OF PHENOLS. PHENOLS COULD BE REMOVED COMPLETELY USING 5% SB-DOPED AFTER 6 H OF REACTION AT 318 K. GENERALLY, WE CAN CONCLUDE THAT PHENOLS COULD BE ELIMINATED COMPLETELY UNDER OPTIMIZED CONDITIONS.
