在太阳光照射下，优化了二氧化钛光催化降解水中具有代表性的内分泌干扰物4，4‘-异亚丙基二苯酚(BPA)的条件。考察了光催化剂用量、底物初始浓度、温度、pH值、光照强度等因素对双酚A光催化降解的影响。最终的降解产物是二氧化碳，从双酚A水溶液中观察到二氧化碳的化学计量形成是完全的矿化。太阳能光催化降解处理方法简单、易操作、价格低廉。因此，由于人造灯具，例如汞-氙灯，在当地和非专属地区特别昂贵，因此所提出的技术似乎是一种非常适合于这些地区包括双酚A的废水处理的方法。(C)2004爱思唯尔B.V.保留所有权利。
The photocatalytic degradation conditions of 4,4'-isopropylidenediphenol (bisphenol A, BPA), a representative endocrine disruptor, in water using titanium dioxide were optimized under sunlight illumination. The effect of various factors, such as photocatalyst dosage, initial substrate concentration, temperature, pH and light intensity, on the photocatalytic degradation of bisphenol A was investigated. The final degradation product was carbon dioxide, and the stoichiometric formation Of CO2 from aqueous bisphenol A solution was observed as the complete mineralization. The solar photocatalytic degradation treatment is simple, easy handling and cheap. Therefore, since the artificial lamp devices, for example Hg-Xe lamp, are particularly expensive in the local and nonexclusive areas, the proposed technique appears to be a very suitable method for the treatment of wastewater including bisphenol A in those areas.
