Abstract :

Wastewater treatment technologies have been employed to remove pollutants in water streams due to the threats that those pollutants pose to human health, animals, and the environment (Khaki et al., 2017). Currently, nanotechnology offers practical solutions to the problems associated with the production of drinking water and with the protection of natural water from being contaminated (Kumar et al., 2020), (Ahmed et al., 2019), (Singh et al., 2018). This study focused on the synthesis of heterogeneous photocatalysis nanocomposite materials that can be used to convert organic dye pollutants in wastewater into non-toxic wastes. Deposition of ZnO on rGO was done by assisted microwave process and incorporation of ZnO/rGO was done by melt-mixing extrusion method. The nanocomposites were characterized using elemental, microscopy, thermal, and photocatalytic analysis by XRD, XPS, FTIR, EDS, DSC, TEM, SEM, and Raman methods. The photocatalytic activity was done by placing nanocomposite into methylene blue solution and measuring UV absorption with time. Recent Publications 1.
