摘要: Titanium oxide coatings(TiO 2 /Ti) were formed on the titanium surface by micro-arc oxidation(MAO) in Na 3 PO 4 solution. The photocatalytic ability of coatings evaluated degradation Rhodamine B aqueous Using TiO /Ti as anod electrode, counter and with UV lamp, constant current meter make up photoelectrocatalytic reactor was built. We have studied effect initial concentration, pH, concentration electrolyte, different anions It is found that impacts conditions are different. With increase removal decreased. also notable, but all them can improve efficiency photoelectrocatalytic. From these studies above, under follows, coating film electrode 5 minutes, 1.5mg/L, value pH three, electrolyte 0.02mol/L, treatment dye wastewater best.
