采用热分解方法制备了铈掺杂钛基电极，并以铈掺杂钛基电极为阳极，纯钛板为阴极组成电解池，以苯酚为目标有机污染物进行降解，采用高效液相色谱法检测苯酚的含量。讨论了Ce的掺杂量、电解池中电极间距、电解电压、电解质溶液的pH、电解质浓度、目标物的浓度以及电解时间对苯酚去除率的影响。结果表明该电解池降解苯酚废水的最佳条件：SnCl4·%According to the principle of thermal decomposition,cerium doped titanium-based electrodes were prepared,cerium doped titanium-based electrode used as anode,pure titanium plate used as the cathode electrolytic tank,phenol used as target organic pollutant degradation,phenol content was determined by high performance liquid chromatography. Effect of concentration of Ce doped amount,electrolytic cell electrode spacing,electrolysis voltage,pH of electrolyte solution,concentration of electrolyte,phenol content and electrolysis time on phenol removal were studied. The results show that the optimal conditions in this test are as follows:SnCl4 · 5H2 O,SbCl3 and Ce(NO3 )3 molar ratio is 100∶10∶1,electrode spacing is 4. 0 cm,electrolytic voltage is 9 V,pH is 6. 55,electrolyte concentration is 10 g/L,concentration of phenol is 100 mg/L,electrolysis time is 6 h. Under the optimum experimental conditions,the phenol removal rate reachea 100%,fully meet the discharge standard of GB 8978-1996. In the next 10 days,removal rate of phenol can still reach 85%.
