Abstract

NANOPARTICLES OCCUR WIDELY IN THE NATURAL ENVIRONMENT. IN THE ENVIRONMENT WE CAN FIND MANY TYPES OF MORPHOLOGIES THAT ACTUALLY ARE SYNTHESIZED, THEREBY AN INTERESTING ALTERNATIVE IS TO OBTAIN AND USE NATURAL NANOMATERIALS. NANOCLAYS IS A REAL ALTERNATIVE TO GET A MATERIAL WITH NANOMETRIC SIZE. THE PURPOSE OF THIS STUDY WAS PRODUCED NANOCLAY FROM MONTMORILLONITE CLAY. SAMPLES, TAKEN FROM CENTRAL ZAGROS WAS PREPARED AND SIEVED TO 2 MM MESH AND AIR-DRIED. ONE PART OF THE SOIL WAS TREATED WITH 30% HYDROGEN PEROXIDE TO REMOVE THE SOIL ORGANIC MATTER. 20 G OF CLAY WERE SUSPENDED IN 100 ML OF 1 M NACL. STIR WELL AND HEAT THE BOTTLE AT ABOUT 80˚C. THIS SOLUTION WAS DISPERSED APPLYING 214 J BY ULTRASONIC DISPERSION. THE SEPARATION OF PARTICLE-SIZE < 2 ΜM FRACTIONS WAS PERFORMED BY SEDIMENTATION PROCEDURES BASED ON STOKE'S LAW. THE NANOCLAYS WERE EXTRACTED FROM MONTMORILLONITE CLAY. THE CLAY SUSPENSION WAS CENTRIFUGED AT 3000 RPM FOR 40 MIN. THE PELLET WAS COLLECTED. THESE WERE MODERATELY STIRRED FOR 40 MIN AND NINE-FOLD WASHED WITH 50 ML OF DISTILLED WATER. MONTMORILLONITE NANOCLAY WAS CHARACTERIZED THROUGHOUT SCANNING ELECTRON (SEM) MICROSCOPY. THE SEM ANALYSIS SHOWED MONTMORILLONITE NANOCLAY SIZE LESS THAN 80 NM AND SHOWED CAVITIES IN THE NANOSCALE. SILICATE LAYERS ARE SEPARATED FROM EACH OTHER AND LAYERS ARE SHAPED PLATE.
