Abstract

CURRENTLY, WASTEWATER TREATMENT DUE TO LOSS OF WATER RESOURCES, INCREASING WASTE AND OTHER HAZARDOUS MATERIALS HAS BECOME A SERIOUS PROBLEM. THE ULTIMATE GOAL OF ENVIRONMENTAL PROTECTION, THE WASTEWATER TREATMENT BY METHODS APPROPRIATE TO THE HEALTH OF HUMANS, ANIMALS AND THE ENVIRONMENT HAS BEEN EVALUATED. DIFFERENT METHODS HAVE BEEN USED FOR INDUSTRIAL WASTEWATER TREATMENT. RECENTLY, DUE TO THE COMPLEXITY OF THESE INDUSTRIES AND ECONOMICAL PURPOSE, THE ADSORPTION METHOD WITH LOW COST AND EASE OF UTILIZATION HAS BEEN STUDIED. INTRODUCTION OF NEW TECHNOLOGIES TO INCREASE THE AVAILABILITY OF CLEAN WATER IS ALMOST FIFTY YEARS AGO. NANO FILTRATION MEMBRANES WERE DEVELOPED DURING THE 1970S AND 1980S. IN THE MEMBRANE PROCESS, USING DIFFERENT TYPES OF MEMBRANES FOR DRINKING WATER PRODUCTION FROM SEAWATER, BRACKISH AND SALINE WATER, WASTEWATER, SURFACE WATER AND GROUNDWATER HAS EXPANDED RAPIDLY. THE INTERACTION OF MINERAL POWDERS WITH REACTIVE SITE OF NATURAL POLYMERS AND MONOMERS RESULT IN A SUPERABSORBENT COMPOSITE. SUPERABSORBENT COMPOSITES BASED ON SYNTHETIC POLYMERS OR NATURAL POLYMERS HAVE BEEN REPORTED.IN THIS PAPER, WE INVESTIGATED THE SYNTHESIS OF NANO COMPOSITES BASED ON POLY (VINYL ALCOHOL) IN THE PRESENCE OF MONTMORILLONITE POWDER USING CARRAGEENAN. THE NANO COMPOSITE STRUCTURE WAS CONFIRMED USING FTIR SPECTROSCOPY AND THE MORPHOLOGY OF THE SAMPLES WAS EXAMINED BY SCANNING ELECTRON MICROSCOPY (SEM). THE INFLUENCE OF THE PARAMETERS, WHICH CAN BE ALTERED GELATION TIME AS A PARAMETER FOR ASSESSING THE OPTIMAL LEVEL OF THE RESULTANT NANO COMPOSITES WAS INVESTIGATED IN DETAILS. THE RESULTING NANO COMPOSITE WAS EXAMINED TO REMOVE CATIONIC CRYSTAL VIOLET DYE FROM WATER. IT WAS REVEALED THAT THE BY INCLUSION OF MONTMORILLONITE NANOCLAY, THE DYE ADSORPTION CONTENT OF NANO COMPOSITE HYDROGEL (NH) WAS SIMILAR AS CLAY-FREE HYDROGEL (H). BUT THE RATE OF DYE ADSORPTION WAS INCREASED.
