Aquatic wastes,containing aromatics are recalcitrant and toxic toward conventional biological treatment.Electrochemical process is an alternative degradation method,which is attractive for environmental compatibility and especially,it is convenient for eletrolysis to be used either as electrochemical degradation or calcification.Anodes with high stability,high activity and low cost are very important for a successful process.Previous work have found that electrodes either based on SnO_2 or minor component of SnO_2 in DSA anodes is quite interesting for its high oxygen evolution over-potential and attractive electro-catalytic characteristics.It was found that when SnO_2 was introduced with Sb into the oxide coating,better electro-catalytic performance was observed.
