In the electrolysis of a soln. contg. glucose, as a model substrate in the wastewater from food industry, and a dil. NaCl, the formation of active Cl makes the glucose mineralization at the stable DSA electrode substantially insensitive to the nature of the electrode surface. The mineralization rate being the same at Ti/Pt, Ti/PbO2, TiSnO2-Pt, and Ti/IrO2 electrode. [on SciFinder (R)]
