Excellent performance of superbead photocatalyst technology for wastewater treatment

Abstract

A novel and excellent superbeads photocatalyst were synthesized and applied to wastewater treatment. Photocatalytic technology has the characteristics of high efficiency, simple process, good reproducibility and easy treatment thus, been chosen to treat the pollutant in wastewater. The synthesized of superbeads photocatalyst of Co3O4 beads, Fe3O4 beads, and TiO2 beads undergo characterization by Fourier Transform Infrared (FTIR) and their performance study by the influence of important parameters such as pH, dosage, and initial concentration were carried out. The highest photodegradation of 88.84% and 87.2% were attained by Co3O4 beads and Fe3O4 beads in the pH 5 with photocatalyst dosage 4.0 g in 2,4,6-tricholorphenol (TCP). Meanwhile, 85.65% of degradation of methylene blue dye was achieved by TiO2 beads at pH 11. These results indicate that these superbeads photocatalysts may provide new tools for solving wastewater treatment challenges with excellent performance. The transformation of these beads photocatalyst enormously improves their permeability, durability, chemical resistance, hydrophilicity, and biological suitability.
