Preparation and Characterization of Ball Clay-Manganese Dioxide Nanocomposites

Abstract

The main problem of the textile industries are releasing the massive amount of dyes in river or other water system. Owing to this badly behaviour results in contamination of underground water and damaging the entire ecological system. The main challenge is treatment of the polluted water without damage of environment. Over the past years, numerous techniques for the treatment of textile wastewater including of membrane filtration [1], ozonation [2], biosorption [3], electro coagulation [4], photo catalytic removal [5], coagulation and flocculation [6], electrochemical precipitation [7]. Nevertheless, these methods having some inadequacy to remove the dyes from wastewater. Nowadays, adsorption technique is a well-known method for the treatment of wastewater from dyes and heavy metals. At present, adsorption techniques have been considered owing to the low cost, ease of operation and less amount of residue. The dyes can be efficiently removed by adsorption technique in, which the liquefied dyes attached themselves to the adsorbent surface. Several adsorbents have been used for removal of dyes from aqueous solution. The adsorbents such as recycled alum sludge [8], waste coir pith [9], fir wood [10], rotton saw dust [11], fly ash [12], coconut shells [13], activatedWe report in present work the simple procedure to synthesize ball clay-manganese dioxide (MnO2) nanocomposites. The as-synthesized nanocomposites were characterized using powder XRD, FT-IR, SEM, TEM and BET surface area, respectively. Recently the explorations of clay modification for developing the adsorbent ability to get rid of the toxins from water. The XRD result indicates that the nanocomposite was crystalline in nature. The FTIR spectra showed that the native ball clay was successfully converted to ball clay-MnO2 nanocomposites, which were identified by the change in peaks. The SEM images of the ball clay-MnO2 nanocomposites showed that development in surface area. The TEM images indicated that the size of the nanoparticle. The BET studies of as synthesized ball clay-MnO2 nanocomposites indicate that surface area, total pore volume and average pore diameter values.This is an open access journal, and articles are distributed under the terms of the Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0) License, which allows others to copy and redistribute the material in any medium or format, remix, transform, and build upon the material, as long as appropriate credit is given and the new creations are licensed under the identical terms.

Adsorption of methylene blue dye from aqueous solution by a novel PVA/CMC/halloysite nanoclay bio composite: Characterization, kinetics, isotherm and antibacterial properties

“…Clay have been successfully employed to develop several nanocomposites whose adsorption capacity matches well with conventional adsorbent. Previous studies show that claybased composites could act as a promising candidate for dye removal studies [58,85].…”
