DEGRADATION OF ORGANIC TOXICS BY ELECTRO-OXIDATION

摘要

This invention relates to an electrochemical process for the degradation of toxic organic molecules in solution. This process includes the treatment of organi c toxics containing solutions in an electrolytic cell having dimensionally stable anodes (DSA) with high oxygen overvoltage. The anodes are made of titanium coated with iridium oxide (IrO2), ruthenium oxide (RuO2) or tin oxide (SnO2). The solution is treated with a current density ranging between 3.0 to 23 mA/cm2 and for a period of time ranging between 10 to 200 min. This process can be used for degradation of different organic molecules including one-type or a mixture of polycyclic aromatic hydrocarbons (PAHs), chlorinate d compounds, pesticides, endocrine disruptors, oils and greases, petroleum hydrocarbons, PCBs, PCDD/F or other types of organic compounds.
