Abstract

In this research, the nanocomposite of perlite@CoO@reduced graphene oxide (PC-RGO) was successfully synthesized fabricated, and characterized by XRD, FT-IR, and SEM images. Diffuse Reflectance Spectroscopy (DRS) was used to find the photocatalytic ability of this nanocomposite. In addition, photocatalytic degradation of hazardous compounds (Methylene Blue) by the prepared nanocomposite under LED irradiation was reported. The effects of pH, contact time, dye and adsorbent concentration and temperature are all taken into consideration. The adsorption kinetics results are adjusted to best fit the pseudo-second-order model. The experimental data are analyzed by Langmuir isotherms. The best results found in the adsorption experiments were pH 11, 10 ppm Methylene Blue, 0. 1 gr adsorbent, and 60 minutes of contact time. The results of experiments show that as-prepared nanocomposite can be applied as a low-cost, accessible Photocatalyst and adsorbent for the removal of organic pollutants from water.
