摘　　要：为了研究渗硼金刚石薄膜电极电化学性能以及用于含有机污染物的废水处理的可行性,采用循环电解的方法,对含苯酚的废水进行了电化学氧化实验,同时与活性涂层钛阳极进行了对比实验研究,考察了阴极的可替代性,最后用两种电极对含苯胺的工业废水进行了对比实验。实验结果表明,金刚石电极不仅具有优越的电化学性能和优异的电化学指标,而且可以用于电化学废水处理;同时,用钛电极代替金刚石作阴极经济可行。The electrochemical oxidation of phenol in an aquatic electrolyte was investigated experimentally using a synthetic boron-doped diamond (BDD) film electrode during bulk electrolysis to explore its electrochemical properties and feasibility for wastewater treatment containing organic compounds. The electrochemical oxidation of BDD electrodes was compared to that of active coating Ti electrodes with industrial wastewater containing anline experimentally. The results demonstrate that BDD electrode has better electrochemical properties and is more suitable for electrochemical wastewater treatment than active coating Ti electrodes. Experiments with BDD anode and active coating Ti cathode were carried out. The results indicate that active coating Ti cathode with BDD anode is more economical.
