摘　　要：在钛基体上电沉积铂制得Pt/Ti电极,用该电极处理甲基红模拟废水,当电流密度为100A/m2,甲基红含量为100 mg/L,在较宽的pH值范围内,电解80 min后,脱色效率几乎达到100%.紫外-可见吸收光谱分析表明,废水处理的矿化程度高.Pt/Ti electrode was prepared by galvanostatic in the quiescent solutions of 5mol/L H2PtCl6 ＋0.5 mol/L H2SO4. Methyl red was catalyzely oxidated by this home-made Pt/Ti electrode. It is found that for a solution of 100mg/L methyl red,almost 100% color was removed,when the pH was about 3,the time of electrolysis was 80 min and the current density was approximately 10 mA/cm^2. The UV-Vis absorption spectra results indicated that the mineralization of the effluent was very high. The electrical energy consumption was about 63.4 W · h · L^-1.
