In this research work, MgO nanoparticles were synthesized by a single-step coprecipitation approach using Kappaphycus alvarezii extract as stabilizer. The synthesized MgO nanoparticles exhibit cubic crystal structure, which were confirmed by XRD and FTIR. The purity of MgO nanomaterials was confirmed by P-XRD. The diffraction crests of MgO nanomaterials are in accordance with customary patterns of pure MgO (JCPDS No.00–004-0821). Electron microscopic analysis demonstrated the appearance of MgO nanoflakes. The UV-DRS was used to calculate the optical band gap of MgO nanoparticles and found to be 4.71 eV. MgO nanoparticles have substantial photocatalytic activity for the deterioration of rhodamine B (RhB) and methylene blue (MB) dyes under visible light irradiation. The experimental data fitted first-order kinetics and around >95% degeneration of both dyes was achieved by photocatalysis using synthesized MgO nanoparticles. Thus, the data obtained from this research can effectively be utilized in large-scale industrial applications during wastewater treatments.
Textile companies release wastewater containing lots of colors including Methylene
Blue (MB) dye. Those colors are harrmful for human well being. Various procedures have
been utilized to expel the color from industrial wastewater. Out of different methods used in
practice, adsorption was observed to be exceptionally successful and effective. The reason
behind the especiality is when nanocomposites are utilized as an adsorbent, as it has a better
adsorption limit, selectivity, and solidness than nanoparticles. In this research, a peculiar
synthesis of adsorbent Graphene Oxide Silica [GO-Si] is carried out and it is used to remove
methylene blue dye from texile industry wastewater. Analysing the performance of MB dye
removal from the waste water using this adsorbent seems to be more effective. Various studies
have been carried out for successful analysis of the performance such as adsorption isotherm
study, Freundlich and Langmuir analysis. In addition the adsorption process was well explained
by a pseudo-second-order kinetics models.
