NPS MAY INTERACT WITH DRUGS SUCH ANTIbioTICS DUE TO THEIR NANO-SIZE AND LARGE SURFACE-TO-MASS RATIO. OF PARTICULAR IMPORTANCE IS THE ADSORPTION OF ANTIbioTIC ON THE NANOPARTICLE SURFACE. MG (OH)2 NANOPARTICLES HAVE MULTIPLE APPLICATIONS IN MEDICINE, INDUSTRY. IN ADDITION, THE MG (OH)2 NANOPARTICLES MAY BE EFFECTIVE ANTIBACTERIAL AGENTS [1-3]...

NANO MAGNESIUM OXIDE IS HIGHLY HOMOGENOUS, ELECTRICAL RESISTANCE AND GREAT MECHANICAL STRENGTH. THEREFORE, NANO MGO OFTEN USED TOGETHER WITH SAWDUST, WOOD SHAVINGS TO MAKE FIRE RESISTANT FIBERBOARD AND OTHER REFRACTORY MATERIALS AS WELL AS METAL CERAMIC WITH ADVANTAGE OF LIGHT WEIGHT, HETEROGENEOUS CATALYSIS, SOUND INSULATION AND THERMAL INSULATION. BESIDES THE USE IN THE WIDE RANGE OF APPLICATIONS, MGO IS AN INTERESTING INSULATING AND CONSTRUCTION MATERIAL OR PHARMACEUTICAL COMPOUNDS [1, 2]. IN THIS STUDY, WE SYNTHESIZED OF NANO MAGNESIUM OXIDE, NANO bioMASS AND NANO bio- composite CONSIDERING ECONOMICAL METHODS IN LITERATURE BY THE PRECIPITATION AND PHYSICAL MECHANICAL METHODS. AFTER SYNTHESIS STAGES, THE SIZE AND MORPHOLOGY OF EACH NANO MATERIAL WERE CHARACTERIZED USING FT-IR, XRD AND SEM. THE RESULTS OF SPECTROSCOPIC AND MICROSCOPIC ANALYSIS REPRESENT MGO bio composite IS NANO SIZE AND HIGHLY HOMOGENEOUS. FINALLY, WE USED NANO bio composite FOR REMOVAL OF DYE POLLUTANTS FROM AQUEOUS SOLUTION.

NICKEL OXIDE IS AN IMPORTANT AND HAS RECEIVED CONSIDERABLE ATTENTION DUE TO ITS APPLICATIONS IN VARIOUS FIELDS OF SCIENCE AND TECHNOLOGY PARTICULARLY IN THE GALVANIZING INDUSTRY TO PREVENT OXIDATION OF METAL SURFACES OR AS CATALYSTS, SEMICONDUCTOR TYPE-P, THIN FILM SENSORS, LIGHT EMITTING DIODES, SOLAR CELLS, FUEL CELLS SENSITIVE [1-4]. IN THIS STUDY, A WET CHEMICAL SYNTHESIS ROUTE ASSISTED BY ULTRASONIC WAS USED FOR FABRICATING BOTH NANO MATERIALS. SO, NICKEL OXIDE NANOPARTICLES (NPS) AND ITS NANO bio-composite WERE PREPARED USING AN AQUEOUS SOLUTION REACTION OF METAL PRECURSOR IN THE FIRST STAGE. THE SECOND STAGE OF OUR STUDY INVOLVES CONFIRMATION OF NANO MATERIAL FORMATION, SIZE, STRUCTURE AND MORPHOLOGY OF SYNTHETIC SAMPLES BY FT-IR, UV-VIS, XRD AND SEM TECHNIQUES. IN THE LAST STAGE, PRODUCED NICKEL OXIDE NPS AND NANO bio composite WAS APPLIED FOR DYE REMOVAL FROM SYNTHETIC AQUEOUS SAMPLES.OPTIMIZATION OF AFFECTING VARIABLES OF THE REACTION WAS PERFORMED BY FRACTIONAL FACTORIAL DESIGN. IN THE PRESENT WORK, IT WAS OBSERVED THAT TWO PROCEDURES ARE EFFICIENT FOR DYE REMOVAL BUT BY REPLACING NANO bioMASS CORES, THE INDUCTIVE COMPONENTS COULD BE MADE SMALLER AND HIGHLY DURABLE- CONTRIBUTING GREATLY TO IMPROVED PERFORMANCE OF CATALYTIC ACTIVITY OF NANO bio-composite IN THE ENVIRONMENTAL APPLICATIONS.
