Abstract

Background: In this study, FORMALDEHYDE degradation rate was investigated through ZnO sonophotocatalist process using an oxidation reactor with a volume of 2 l.Methods: This was a fundamental, applied, and cross-sectional study. During various experiment steps (30 steps), the influence of important operational parameters, such as solution pH (3-8), initial CH2O concentration (20-100 mg/l), ZnO NANOPARTICLEs dosage (10-60 mg/l), ULTRASONIC wave power (40-150 W), and reaction time (10-60 minutes), was investigated.Findings: Maximum FORMALDEHYDE removal ratio (78%) occurred with a ZnO dosage of 60 mg/l, solution pH of 8, ULTRASONIC wave power of 40 W, initial FORMALDEHYDE concentration of 50 mg/l, and a contact time of 30 minutes.Conclusion: It can be concluded that the sonophotocatalytic process is effective in the treatment of solutions containing low FORMALDEHYDE concentrations.
