摘要

The speedy industrialization and explosion of the populace consequences in raised usage of potable water and its resulting disposal causes ecological contamination. Though, the graphene oxide (GO) and ceramic material namely MgO were reveals the low dye adsorption capacity in the field applications. The GO and MgO materials have very fine particles causes the pressure drop during filtration, so it reduces the adsorption capacity. To conquer this issue and improve the surface area, the GO and MgO materials combine with clay (KA/HT) and biopolymers hybrid material was developed for improving adsorption capacity. Herein, GO and MgO fabricated hydrotalcite (HT)/kaolin (KA) supported alginate (Alg) and pectin (Pect) which gives GO/MgO/HT-KA@Alg/Pect hybrid material for the adsorption of malachite green (MG) and methylene blue (MB). The hybrid composite possess the stable and easy filterable nature for the adsorption of MB and MG dye. The adsorption isotherm investigation reveals that the hybrid composite possesses the adsorption capacity of 42.00 and 40.50 mg/g for MG and MB dyes within 40 min. The enhance adsorption was noted at a pH level 9 for MG and MB and its reached equilibrium at 40 min. The synthesized hybrid material was characterized by FTIR, SEM and EDAX studies. In addition, dye adsorption mechanism of hybrid material was also discussed in detail. The dye adsorption was followed by Langmuir isotherm and pseudo-second-order models. The fabricated material can be revealed as a proficient adsorbent for water/wastewater treatment method because of the high dye adsorption and reusable efficiency.
