Methyl orange (MO) is an environmental concern because their degradation products are highly toxic to aquatic microorganisms and carcinogenic, also their degradation products are mutagenic to humans. Electrochemical oxidation is one of the promising technologies for the dye wastewater de-pollution, which are obtained extensively attentions because it holds the advantages of total oxidization of dyes to CO2 and H2O. Titanium dioxide has emerged as the leading candidate to provide complete destruction of organic pollutants via heterogeneous photocatalysis that result in total mineralization of many organic pollutants. Though this process offers actual annihilation of the dye moleculesatavery high efficiency, thepost-treatmentrecoveryof TiO2 canbecostly. The titanium nanotubes are typically produced by anodic oxidation of the titanium foil in various electrolytes.Degradation of methyl orange (MO) was conducted by electrochemical oxidation method with Ti/TiO 2 nanotubes anodes. Were prepared samples of TiO2 nanotubes by anodizing titanium in an electrochemical bath consisting of 1:1 waterglycerol with 0.4% of HF using different conditions: 25V for 8 hours, 30V for 3 hours in the stationary state, 30V 3 hours under ultrasound stirring. The oxidation efficiency was determined by UV-VIS analysis of the electrolyte.
