Novel Anodes for Pollution Control

采用多孔钛衬底制备高表面积掺杂氧化锡电极；掺杂剂包括锑、铋和砷。电极作为电解苯酚、苯胺、EDTA和氯苯酚的阳极进行测试。有毒的有机化合物存在于许多工业的废物流中，包括纺织、石油产品、纸浆和造纸以及有机化学品。目前的方法要么无法将浓度降低到可接受的水平，要么产生有毒的固体废物，从而造成另一个问题。在许多情况下，有效的电化学破坏可能是一个有吸引力的选择。

High-surface-area doped stannic oxide electrodes are prepared using porous titanium substrates; the dopants include antimony, bismuth, and arsenic. The electrodes are tested as anodes for the electrolyses of phenol, aniline, EDTA, and chlorophenol. Toxic organic compounds are present in the waste streams of many industries, including textiles, petroleum products, pulp and paper, and organic chemicals. Present methods are either unable to reduce concentrations to acceptable levels or produce toxic solid wastes that pose another problem. Efficient electrochemical destruction may be an attractive option in many cases.
