چکیده
Industrial processes are among human activities that cause production of a large volume of wastewater containing organic pollutants such as phenol and its derivatives. Soil remediation is crucial for enhancing environmental quality for both humans and other living organisms. This study investigate the use of an electro-peroxone system to remove environmental pollutants from soil. In conjunction with ozonation, the study employed electrochemically generated hydrogen peroxide using a carbon electrode, addressing concerns about transportation and storage. Experiments were structured using response surface methodology (RSM) with three variables: ozone dosages ranging from ۴ to ۸ l/h, initial pollutant concentrations from ۲۰ to ۵۰ mg/kg, and treatment durations between ۷ and ۱۴ days. The effectiveness of phenol removal from soil was assessed by applying a consistent voltage of ۲ V/cm to the soil samples in all experiments. Results revealed a negative correlation between initial pollutant concentration and ozone consumption and a positive correlation between treatment duration and pollutant removal efficiency. Optimal removal efficiency occurred with a ۱۴-day treatment duration, an ۸ l/h ozone dosage, and a ۲۰ mg/kg initial pollutant concentration. The electro-peroxone system's application indicates its potential as a sustainable, eco-friendly, and cost-effective approach to soil remediation for pollution.کلیدواژه ها
