REMOVAL OF CATIONIC ORGANIC DYE FROM THEIR AQUEOUS SOLUTIONS EFFICIENTLY AND SELECTIVELY BY MAGNETIC NANOPARTICLES FABRICATED HYDROGEL

Abstract

In recent time, treatment of wastewater is the main concern for the life on earth. One of the major factors of waste water is organic dyes that lead to serious health and environmental threat to the ecosystem. Various methods were developed for removal of organic dyes from wastewater, adsorption is among the efficient and cost-effective technique. There are numerous varieties of adsorbents were used but I chose hydrogel Nano composites to enhance the adsorption capacity. Using a hydrogel made of poly (acrylic acid) grafted onto Xanthan and guar gum (FeO-XG-GG-AA) and magnetic iron oxide nanoparticles (FeNp); a novel biocompatible magnetic iron oxide nanoparticle/hydrogel was created in this study. By using scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDAX), X-ray diffraction, Fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), and UV spectroscopy, the structural, morphological, and magnetic properties of the optimized sample were characterized. The results show the hydrogel strength and stiffness are both increased by the addition of inorganic filler to the hydrogel polymer matrix which is more way powerful than that of a normal hydrogel. The magnetic Nano composite hydrogel has a way too much potential to be used as an adsorbent for the removal of CV dye from aqueous solution.
