چکیده مقاله:
Organic dyestuffs in wastewater from many industries including textile, paper, leather, and plastics have been discharged to the environment causing serious soil and water pollution due to biological degradation, high chemical oxygen demand (COD) of the water body and inflected toxicity on humans 1. Among various dyes, methylene blue (MB) as a toxic cationic dye is difficult to degrade due to its stability to light and oxidation reactions and is often employed as a model dye of organic pollutant 2. Therefore, the removal of organic dyestuff from wastewater becomes environmentally important. Among the various methods of dye removal, adsorption technique is regarded as one of the ecofriendly and effective method because of simplicity design/operation, high efficiency and harmless to treated water 3. In this study, we synthesized a novel magnetic organic-inorganic hybrid nanoadsorbent by incorporating anionic surfactant of sodium eicosenoate (SEIA), cationic surfactant of cetyl trimethylammonium bromide (CTMAB) and magnetic Fe3O4 nanoparticles into the interlayer of Mt. Subsequently, the modified Mt was used for the removal of MB from aqueous solutions and operational conditions for MB adsorption were studied.
