Electrochemical Treatment of Petroleum Refinery Wastewater Using SnO2 and Graphite Anodes
Abstract
In recent years, clean water has become increasingly scarce because of the highly consumption by human and industry. Therefore, a huge amount of wastewater was discharged to the environment and their treatment is essential by using cost-effective methods. In this study, wastewater from petroleum refinery was processed by an electrochemical oxidation using two types of anodic materials graphite and SnO2 film deposited on Cu substrate. SnO2 anode was prepared from nitrate media and characterized by XRD and SEM. Experiments were conducted to determine the performance of each electrode at a current density of 12 mA/cm2 in the absence of NaCl addition. The SnO2 electrode showed better processing ability than the graphite electrode at the same current density in case of no addition of NaCl. Addition NaCl resulted in increasing the activity of graphite in the treatment of wastewater but never exceeded the efficiency of SnO2. The best removal of chemical oxygen demand (COD) at a current density of 12 mA/cm2 and 150 min was 79% in case of SnO2 in comparison with 72% in case of using graphite with addition of NaCl. Energy consumption in case of SnO2 was 9.93 kWh/kg COD which is very low in comparison with the using of graphite (49.6 kWh/kg COD). The decay of COD was found to obey pseudo first order for anodic oxidation using SnO2 or graphite electrodes.
期刊介绍:
Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas.
Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
